Document loading failed - and "Bad URI syntax" logged in Collabora container

ℹ️ Support 📄 Office

First of the installation is done using the Nextcloud AIO, and all other features are working including other websocket connections.

I’ve substituted my real domain with cloud.example.com

When trying to access documents I get the “Document loading failed” and looking at the requests the one failing is:

wss://cloud.example.com/cool/https%3A%2F%2Fcloud.example.com%2Findex.php%2Fapps%2Frichdocuments%2Fwopi%2Ffiles%2F19_ocnwpekhy9bs%3Faccess_token%3D9rwaLW2Gga0ehiyKlVEL6MB0WrumwcVp%26access_token_ttl%3D0/ws?WOPISrc=https%3A%2F%2Fcloud.example.com%2Findex.php%2Fapps%2Frichdocuments%2Fwopi%2Ffiles%2F19_ocnwpekhy9bs&compat=/ws

This one is returning a 400 Bad request

Looking in the nextcloud-aio-collabora container logs the following entries show up:

2024-08-04 11:03:35 wsd-00007-00019 2024-08-04 09:03:35.139378 +0000 [ websrv_poll ] ERR  #80: #80 Exception while processing incoming request: [GET /cool/https:/cloud.example.com/index.php/apps/richdocuments/wopi/files/19_ocnwpekhy9bs?access_token=9rwaLW2Gga0ehiyKlVEL6MB0WrumwcVp&access_token_ttl=0/ws&WOPISrc=https%3A%2F%2Fcloud.example.com%2Findex.php%2Fapps%2Frichdocuments%2Fwopi%2Ffiles%2F19_ocnwpekhy9bs&compat=/ws HTTP/1.1 ...]: Bad URI syntax| wsd/ClientRequestDispatcher.cpp:893

I’ve gone over the proxy settings referred to in Proxy settings — SDK https://sdk.collaboraonline.com/ documentation
And How to debug problems with Collabora and/or Talk · nextcloud/all-in-one · Discussion #1358 · GitHub
Everything seems as it should, the settings page also show OK

Is there log entry in Nextcloud?

What version of the richdocuments / Nextcloud Office integration app?

No error logs, the last logs are from when I rebooted the containers and retried accessing a document:

The only I find odd is that there only is that there is only one / in the ...https:/cloud... part of the request. In the original request %3A%2F%2F should resolve to :// but the proxy only seems to see :/

Found the issue, there was an issue with IIS ARR / URL Rewrite and having multiple ? some parameters got lost.
The fix is to use {UNENCODED_URL} instead of {R:1} in the rewrite and not enable Append query string
