Nextcloud version (eg, 18.0.2): 20.0.2
Operating system and version (eg, Ubuntu 20.04): Linux 5.4.72-v7l+ armv7l
Apache or nginx version (eg, Apache 2.4.25):

The issue you are facing:

Is this the first time you’ve seen this error? (Y/N): Yes

Steps to replicate it:

  1. Because I had problems syncing with the Desktop Client I switched off E2E-Encryption.
  2. Now the Upload of any files does not work on any client, if the file is bigger than 15kB. Downloading the existing files still works.
  3. Switching E2E-Encryption on again did not work.

The old topic originates before Nextcloud split from ownCloud, therefore the guideline from early after the split should still be valid:
