Unable to connect to server with Base64 image set

luhzifer · July 8, 2023, 9:51am

Hey guys, i cannot get around this issue and dont really understand the problem. After we update our clients (doesnt matter if it’s linux or windows) to 3.6.0, we cannot connect to the server any more. But we can connect to other servers with the same version (3.13.7 @linux x64)… I will attach the logs from server / client but theres not that much to see.
Can anyone halp?

Thanks in advance!

Edit:
When someone with a downgraded client (3.5.6) is connected, he can see the updated clients connect but then they disconnect after some seconds or a minute… On updated client’s side it just says ‘error’ after a while

Have you tried any other server?

Has target server the the ts3init_linux_netfilter_module ruining and maybe is misconfigured?

luhzifer · July 10, 2023, 9:42am

I can connect to other servers - no to all tho. I tried connecting to a freshly made ts3 server running in a docker, which i couldnt connect to either.

how can I see whether the module is installed or not?

TS.ChrisR · July 10, 2023, 9:48am

Try one of the mentioned commands from the GitHub page.

Edit
If the netfilter module is not installed, then i have no idea why only older clients should be able to connect to server 3.13.7. Works just fine here and for other users with 3.6.0 running.

luhzifer · July 10, 2023, 10:24am

Thanks for your reply. So the netfilter module is not running and I guess I’ll have to figure it out by myself then ^^

The weird thing is that we all did nothing but update the client via ‘update available’ message and clicking ‘yes’…

luhzifer · July 10, 2023, 10:53am

Ok, I just found out, that renaming the ts3server.sqlitedb file makes connecting possible again… Is there any way to tell, what exactly got messed up?

TS.ChrisR · July 10, 2023, 11:00am

Renaming the database file will force the server to create a new one.
Hope you did not rename it while server is running!!!!!!!!!!!!!!!!!!.

BUT you wrote you made a new Docker server and you could not connect.
There wasn’t any database at all in that case. Like you had no when you renamed it.

I can’t tell what happened. And I won’t tell you to go into the database and do anything in there.

luhzifer · July 10, 2023, 11:17am

ok so there is not anything like a repair db tool or something?

TS.ChrisR · July 10, 2023, 11:26am

In the server there is only one feature to prevent client’s with older version to connect and you would get a message and not a timeout. You are not seeing a message and older clients can connect. So this feature wasn’t touched or is working fine.

The database is never to be touched!

When you have a backup of your database, then use that one.

luhzifer · July 10, 2023, 11:47am

i have a backup but… I dont understand why i can connect with 3.5.6 and cannot with 3.6.0

By renaming/removing the sqlitedb file it enables me to connect with 3.6.0 client

luhzifer · July 10, 2023, 11:59am

Ok I found the problem…

It was the Hostbutton Icon URL (edit virtual server - Hostbutton - Icon URL)
There was entered an URL with like the raw image data or stuff, that worked with 3.5.6 but not with 3.6.0 anymore… no idea why. If you want to investigate: Heres the text that was in the box

It’s an Base64 image.

I can reproduce it with any picture when it’s Base64. No sure if that should work at all.
But it did and doesn’t on latest TS3 or TS5

Guess the length of it breaks it. This small A works fine.
