Hi danield,
Correct. My solution at:
deals with the identical problem.
My contribution also provides the solution.
(I only didn’t find the “solved” button )
You only must use the Script at the bottom and it works after any reboot, if you call it in teh crontab file (@reboot).
If the onlyoffice container restart without a system reboot, you must run the script manually.
If something is unclear, just write to me.
Bye, Migo
