Connection Test Failing

[johnrmcinerney]

hey guys ---

I've been running FG for over 3 years now, with nary a problem. Today, my connection test failed and I'm baffled as to how this could happen. Is anyone available to help me with a walkthrough for this problem?

Thanks. I truly appreciate it.

John

Sorry John - I gotta get some sleep.
If its been working ok in the past - try rebooting your router
If you did any configuration initially to make it work then also check what IP the port forward rule is pointing to and what IP your computer has.
Good luck!

[johnrmcinerney]

I did nothing to configure it for use originally. Its been working fine from Day 1. I reset my modem and router and its still a no-go, buckaroo.

[Myrdin Potter]

Can you provide some details of how you connect to the internet? Generally you need to do port forwarding from your router, are you sure you did not do that when you first got it and it has just been working ever since?

What operating system do you use?

[midas]

The most common reason I've seen cause the "it was working and now it isn't" issue is that the router was configured to forward inbound traffic to the computer's IP address, and that IP address has changed. For example in the past you may have set it up to forward traffic to 192.168.1.101 and now your computer has 192.168.1.102.

[damned]

please do the following command in a command prompt:

tracert 8.8.8.8

and post here. if you would like me to look with you please send me your email via PM.

I have a game with three other players - all of us from all of our locations are not able to connect to me, or to each other and all "Run Test" are failing. Three locations all have been working before.

I am not 100% sure what the question here is. You all have at least the full license, you each have been running games in the past, and now no one can connect to each other?

Are you all using the same isp and are close to each other?

Do all of you have a Standard License or better?

You will need to tell us more. Have you checked your port forwarding and internal IP? Can you post tracert info like above? You can also check out the Discord server and see if anyone in the support channel can help out realtime.

[Gollwyn]

Heya,

I have Ultimate license (the kind where I can host even trial folk). Two of my friends have either standard or the same. Two of us are in Atlanta, one in Boston, one in Las Vegas. We all connect weekly, and I reconfirmed my firewall is open on 1802 (no change since last game).

Not only can they not connect to me via IP or alias, but none of us can connect to each other on any front. Additionally we are none of us able to get a successful "Run Test"

thanks for the help!

[Gollwyn]

Can anyone connect to anyone? :) - I was able to connect to a localhost from a VM on my desktop to the game - I just can't connect to anything outside.

[Gollwyn]

Update: My one friend on trial was able to host the demo campaign and I could connect to it from here. But he can't connect to my licensed version. Is there possibly an issue with license server?

[Zacchaeus]

If everyone has the standard or better license then you can all connect to each other (not at the same time obviously). Demo users can only connect to an Ultimate license holder or if the DM has a Standard license one demo user (only) can connect.

Everyone that hosts must have port 1802 forwarded and have their AV whitelist FG and any other firewalls etc must similarly allow FG.

[Gollwyn]

Yes, we are familiar with the port situation (We've been playing this way for months). I was just able to connect to one friend hosting the demo campaign on a trial license - but he can't reciprocally connect to me. Does FG connect peer-to-peer or is there a call to a central server/license server?

And wow! Thanks for the quick replies.

[Zacchaeus]

Yes, your license is verified when you connect. But the connection is Player to DM. I wasn't aware that you could connect to a demo user though.

[Zacchaeus]

If you can also do a tracert to 8.8.8.8 and post the results that might be helpful.

[Myrdin Potter]

You need the port open and forwarded to you (I assume you are the DM). Do you know if you have the same internal IP address in your router that you did when you forwarded the port originally?

[damned]

Most likely your IP address is no loner the one that is set in Port Forwarding - check and confirm.
Next most likely is your Network (in Windows) has changed to Public or something similar - change it back to Private/Home.

[Gollwyn]

Update: I think it was a connection to license server problem. We were able to establish test connections to demo campaign, but not to real hosted campaign. No changes made to firewall, but it just started working again. My guess? License server down and/or ISP routing table changes to license server. My IP did not change.

Hi all,

I recently got Fantasy Grounds and tried to set it up to host a game, but I'm having connection test failure. I set up my router, Port Forwarding 1802, but I'm not using a static IP, should I set it up like that? My firewall is off and I'm still getting failure. I'm a bit of a noob so sorry if I can't explain things well. I'm running FG on windows 8 on mac bootcamp. I also tried on mac with Winery but still got failure.

Thanks,

Slarti

Welcome to the forums and FG community.

Do you have a modem between you and your router? Where in the world are you, some countries have switched to using ivp6 protocols which messes with having a success. If that is the case you will need a VPN till the Unity re-write comes out.

[Slartibartfat]

I didn't explain properly. No I have a cable internet connection with a modem/router. I'm currently living in Turkey, maybe they have something that prevents me from doing it. I set up my port forwarding again, I don't have a static IP, but I included my local IP and the external IP (the port forwarding on the router seems to need both), chose both TCP and UDP protocols and ticked "Enable".

Not sure what else I'm supposed to do.

Change all the ports to 1802, in "Local IP" put the IP address of your FG computer. Leave external IP as 0.0.0.0.

Unfortunately, after doing all that, it still does not work, and I can't understand why. A friend of mine in Scotland did it all with the same settings and it worked fine for him. I'm using a Netmaster Infinity 401. Should I change the Network settings on the Mac?

DHCP / DHCP with manual address / BootP / manually ? these are the options I see.

Sorry guys but I really can't seem to solve this.

[damned]

You can use the Network Utility application, which is included with Mac OS X, to run trace route.

Launch Network Utility.

You can do this through Mac OS X Spotlight by typing Network Utility, and then clicking the Top Hit.

Click Traceroute.

Enter 8.8.8.8 and Click Trace.

Copy the results and paste here please.

[Slartibartfat]

Thanks for the help. Here goes:

Hi Slartibartfat if you login to your router what are the first two sets of numbers of the routers WAN interface?

[Slartibartfat]

Is this it?

https://www.fantasygrounds.com/forums/attachment.php?attachmentid=22410&stc=1&d=1519463072

[damned]

That looks ok so you need to:

1. Create a port forward rule TCP 1802 (if its a range its 1802 - 1802) to your computers LAN IP on TCP 1802.
2. Make sure your network profile is set to Private
3. If you have an Antivirus app with a firewall make sure there is a rule to allow FantasyGrounds.exe to receive inbound traffic.

[Slartibartfat]

I created the port forward rule, I don't have any Antivirus app running (as I have mac), but I checked my firewalls both on the computer and on the router and they are all off. The only thing I'm missing is setting my network profile to private, where do I do that? Sorry for being such a noob..

I keep trying canyouseeme.org to check the port too and it always says ERROR...

[Slartibartfat]

I also have FG installed on my Bootcamp Windows partition so I can try doing it from there if it's better.

[Trenloe]

I keep trying canyouseeme.org to check the port too and it always says ERROR...
When you try canyouseeme.org for port 1802 make sure FG is running, with a campaign fully loaded waiting for players to connect. This is the only time port 1802 will be listening for connections.

[damned]

Slartibartfat send me your email address via PM and I will have a look with you.
Do note our time zone differences...

[Bidmaron]

I bet he has multiple routers

I bet he has multiple routers

The image he posted shows a public ip address on his wan interface:

[Bidmaron]

Oops I missed that.

[Slartibartfat]

So, in the end we will be using Hamachi because of my network showing two different external IPs. I'm sure "damned" can explain it millions of times better.

All I can say for posterity is that if there are any GMs that live in Turkey, they will probably have the same problems. Thanks so much for all the help and have fun! We certainly will.

[damned]

So this was a new one. At first I thought - Turkey - they might not have a lot of IP addresses - definitely going to be some IPv4 aggregation going on but a search suggested around 10million IPs assigned to Turkey and the WAN IP looked good to me...

Turns out that at some point the IP Range: 100.64.0.0 - 100.127.255.255 has been designated for internal provider use only.

"This block is used as Shared Address Space. Traffic from these addresses does not come from IANA. IANA has simply reserved these numbers in its database and does not use or operate them. We are not the source of activity you may see on logs or in e-mail records. Please refer to https://www.iana.org/abuse/ "
"Shared Address Space can only be used in Service Provider networks or on routing equipment that is able to do address translation across router interfaces when addresses are identical on two different interfaces. "

So... they are aggregating his link and we went with Hamachi.

"Change all the ports to 1802, in "Local IP" put the IP address of your FG computer. Leave external IP as 0.0.0.0." This line solved my problems, not that you knew I had issues :)

Thanks Trenloe
