Hey,

this looks to me related to the enabled encryption. Personally i would open a bugreport at the ownCloud bugtracker.

janholubek · March 28, 2019, 12:50pm

Hi,

thanks for your answer. We’re gonna switch the encryption within the next weeks, so maybe the problem gets solved.

Meanwhile I’m still thankful for other thoughts

janholubek · April 18, 2019, 7:44am

@tom42 Thanks again, indeed the migration from User Key to Master Key solved the problem.

janholubek · May 2, 2019, 1:09pm

Unfortunately I was wrong, it worked for some hours when the encryption was disabled, now we have the same problem again. I opened an issue on github.
