A message keeps appearing in the system diagnostics. This is the variable:
has an invalid value. In fact, this variable has no value. If I enter 80, the message disappears. From time to time, I assume after an update, the message appears again. When I then check, the variable again has no value.
Access to Nextcloud via HTTPS works without any problems. What is this variable for and what value do I have to set so that the message disappears permanently?
