The issue you are facing:
the android app is not uploading files (also tried to make a new folder) and gets permission errors. this happened for me and my wife (different types of phones)
Is this the first time you’ve seen this error? (Y/N): N . been happening for at least a week, probably more.
Steps to replicate it:
-
open app
-
go to uploads to see the failed uploads
-
hit retry, and they fail, all the time
-
go to files
-
hit
+and create a new folder… fails (permission error)
The output of your Nextcloud log in Admin > Logging:
seems like a lot of sensitve data in here, but when looking at the logging gui, i tried to upload on the phone, it failed. refreshed the logging page, and there were no new entries…
