I have the same problems with this. I also solved this so that onlyoffice is on its own server and through reversy proxy at public internet. After that filerun will be recognized and there will be no white page

Solved.

I'm too tired... remember to turn off the settings for instant

notifications and then do something that creates a database log and then

scan the script

or does this have to do with the license because the other server works with the license?
