Summary of the issue you are facing:
I have Euro-Office document server (version 9.3.1, manually downloaded and installed the amd64 release), running on port :80. My Nextcloud instance works nad is running on port :81. I can curl http://:80 & :81 successfully with no errors in the terminal.
As per the integration instruction here: GitHub - Euro-Office/eurooffice-nextcloud · GitHub , I navigate to ~/settings/admin/eurooffice in the Nextcloud web application, and fill out the form as follows:
Nextcloud Office Address: http://<server-ip>:80/
âś“ Disable Certificate Verification
Secret Key: Retrieved from /etc/euro-office/documentserver/local.json
When I submit the form, I get the error below:
Request Failed with Status Code 500
I’ve tried changing from port :80 to :8080, restarting nginx, restarting my server, reinstalling euro-office
Steps to replicate it (hint: details matter!):
-
Change Nextcloud port with
sudo snap set nextcloud ports.http=81 -

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
