Player cant connect since last update

[BartoloMaeusAT77]

Hi. loaded the new FGU Update today. Server (Ultimate) + Clients (1 Ultimate + Free). This is the first problem ever with FGU.

Is there a problem with the linux client?

OS: Linux Mint
FW: off for test, no blocks.

Since that no login from the player are possible. I'm connected to the lobby, the player can see my game but i got repeated lines in network.log:

Your mono runtime and class libraries are out of sync.
The out of sync library is: /home/pos/.smiteworks/fantasygrounds/FantasyGrounds_Data/Managed/System.dll

When you update one from git you need to update, compile and install
the other too.
Do not report this as a bug unless you're sure you have updated correctly:
you probably have a broken mono install.
If you see other errors or faults after this message they are probably related
and you need to fix your mono install first.

We'll need to see the whole logs. Please compile the logs after you encounter the issue and attach the result ZIP file here. Details on how to compile the logs are available in the FG Wiki here: https://fantasygroundsunity.atlassia...o+Compile+Logs

Not sure where the problem is, I tried a complete new install - same problem. Player cant connect to me, I cant connect to player.

I noticed the non-English letter in your campaign name "Steinväter". I imagine this is not new, but I wonder if it makes a difference if you use only core English letters. It's a WAG I know, but might be worth testing if no one else has ideas.

[BartoloMaeusAT77]

I thought the same, maybe something changed with the last update. Tested it by creating a new campaign called "ConnectionTest". Players could see it, but not connect (Same as the one with the "ä").

[LordEntrails]

Can any user connect? You can ask on Discord, someone is bound to be available. I'll go hang out in the support channel while I can.

[BartoloMaeusAT77]

Sorry, I gave up yesterday, read the message too late. Otherwise, I would have responded earlier.

I was able to find the issue today.

Short version: If players can see your campaign but can’t connect => check your IPv6 connectivity.

Here’s a short explanation of what happened, as it might affect other Linux users in the future:

Yesterday, I tested the entire LAN again. At some point, I realized that FGU also shows IPv6 connection infos on startup. A quick test showed that IPv6 was down (loopback wasn’t working, ...). This was odd since I never disabled IPv6.

When I logged into my Fritz!Box 5590 Fiber, I was greeted with a message saying that my "provider had installed an update". These updates are released by the provider without prior notice and are enforced without the user’s awareness. For some reason, the new version had IPv6 in the LAN disabled (thanks Vodafone). Of course, this happened right around the same time I updated FGU to version 4.5.10 between two game sessions.

As a result, Linux didn’t initialize IPv6. After re-enabling IPv6 in the fiber modem, FGU is working as it did before.

Something I’ve always wanted to say: Thank you for releasing FGU on Linux!
