I tried to install Collabora Online on my Nextcloud (12.0.0) following the instructions here : https://nextcloud.com/collaboraonline.
At first I had an issue with docker similar to https://help.nextcloud.com/t/collabora-docker-capabilities-problem/4774, I switched to devicemapper as explained and it fixed this part of the bug.
Now when I click on an office file on my nextcloud, it opens and empty Collabora page, as shown in this screenshot:
No errors are displayed, but if I look at the console log I found that the exange with the office hosts ends with two 404 errors on the following address:
When I directly access this url on my browser I haven't a
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /lool/https://nextcloud.domain.fr/index.php/apps/richdocuments/wopi/files/FILEID.
Reason: Error reading from remote server
Nothing appears in the logs when I use nextcloud normally, however when I access directly to the faulty url, I got the following error on the docker's log:
wsd-00026-00034 12:23:39.149842 [ websrv_poll ] ERR #20 Exception while processing incoming request: [GET /lool/https://nextcloud.domain.fr/index.php/apps/richdocuments/wopi/files/58_o...]: Syntax error| wsd/LOOLWSD.cpp:1665<something_that_look_like_an_id>&access_token_ttl=0&permission=edit/ws HTTP/1.1
I tried to restart my docker using differents values from
-e 'domain=...', including
-e 'domain=nextcloud\\.domain\\.fr' with and without the double backlash,
-e 'domain=.*\\.domain.fr', and some inexistant subdomains of my domain, it never changed the behavior ...
Does someone have an idea of what might be occurring ?
