Collabora race condition

[thxrben]

Hey folks,

I am stuck having collabora online on a race condition where the connection is "just closed":

docker run -t -d -p 127.0.0.1:9980:9980 -e 'aliasgroup1=https://XXX.com:443' --restart always --cap-add MKNOD collabora/code

I have the 127.0.0.1:9980 proxied outside with https and apache2 as a reverse proxy is also proxying with https towards the collabora server (websockets too).

When trying to open a document, this happens in the logs of nextcloud:

nextcloud-nc-1     | 172.17.0.2 - - [14/Oct/2024:12:50:11 +0000] "GET /index.php/apps/richdocuments/wopi/files/429_ocfbhm7lx6ve?access_token=TOKEN&access_token_ttl=0 HTTP/1.1" 200 2392 "-" "COOLWSD HTTP Agent 24.04.7.2"
nextcloud-nc-1     | 172.17.0.2 - - [14/Oct/2024:12:50:11 +0000] "GET /index.php/apps/richdocuments/wopi/files/429_ocfbhm7lx6ve/contents?access_token=TOKEN&access_token_ttl=0 HTTP/1.1" 200 14419 "-" "COOLWSD HTTP Agent 24.04.7.2"

With 172.17.0.2 being the docker IP (on the same host) of collabora.

Collabora itself prints this:

I cannot get collabora to respond to nextcloud correctly, and wasnt able to find any logs online that mention "Unusual race" or "SessionState::WAIT_DISCONNECT" at all.

If you have any ideas, please let me know. Thank you!
