Question to Teamspeak 3 with Docker and MariaDB

Ok, my TS3 is running but even with opened 30033 no file transfere is possible but why?

Has this smth. todo with the mounted files volume? Because even with 777 an uploaded file e. g. Icon/Avatar gets a size of 0 and the client tells me that it couldn’t open a file transfere pipe and assumes that the port is not open but it is definitly open since “lsof -i -P -n” kists *:30033 (LISTEN) on IPv4 and IPv6.

Any ideas, what the problem could be?

It seems the permissions of the folder are somehow reset to 700 or something like that.
Make sure the uid inside the container is the same as the one that the folder belongs to.

but it actually is really weird…
I uploaded filed to my docker server with a mapped directory.
I cleared my entire TeamSpeak cache.
The files were still found on the server.
I am not able to locate the icons anywhere inside the mapped directory and not even the container…

Ok, this is so stupied … don’t know why but my provider (Hetzner) is blocking 30033 and since I changed it to another one, it is working just fine … interesting that such things can happen.
