I have a downgrade workaround for now…thanks @transocean for raising the issue!
yum downgrade https://github.com/ONLYOFFICE/DocumentServer/releases/download/ONLYOFFICE-DocumentServer-5.0.7/onlyoffice-documentserver.x86_64.rpm
Those who installed from howto have to do the steps again from executing the configure script:
# documentserver-configure.sh
If you are using the nethserver-onlyoffice module just do
signal-event nethserver-onlyoffice-update
I had to disable and enable the onlyoffice app in Nextcloud to make it visible in the settings.
Thanks @dnutan, I put the missing file back and could only see the nginx default page. I’ll try the config file from your link.
I am going to provide a more stable package/howto without onlyoffice repo dependency but it may take some time…
