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
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?
