PBS 4.1.0 - no output in task status window

[Str1atum]

Since 4.1.0 I have no output in the task status window. Syslog shows the progress even in Web GUI, but not in the task detail window.
Note this happens only when accessing through traefik and not when accessing directly in local network. But the shell works fine, which I suppose should use websocket as well.
In PVE the equivalent dialogue works fine as well when accessing via traefik.

nobody experiencing that problem?

Same issue here.
For me, it also only happens when using a reverse proxy (Traefik) to access PBS, everything works normal when accessing PBS via IP.

There is nothing in the PBS logs.

When trying to open the logs for the Garbage Collection tasks, the browser console shows these 2 entries repeatedly:

Traefik debug logs show:

Rejecting request because it contains encoded character %5C in the URL path: /api2/json/nodes/REDACTED/tasks/UPID%3AREDACTED%3A00000274%3A000001CF%3A00000022%3A693CC8A0%3Agarbage_collection%3Apbs%5Cx2dnas01%3Aroot%40pam%3A/status

I was able to resolve the issue for now by allowing the encoded character "%5C" (backslash) in the request path.
