Port set to 0 instead of 443 when setting up a Google calendar thus no sync

[TomiOhl]

What Happened?

Set up my Google calendars via the Calendar app. The events weren't being synced. So I compared the config files in .config/evolution/sources with the files on my other machine, where I set up the calendar two years ago. One line was different: under [Authentication], Port was set to 0 in the new config and 443 in the old (working) config. I set it to 443 on my new machine and it immediately worked.

Steps to Reproduce

1. Set up google calendar sync from the Calendar app
2. Notice that events aren't synced
3. Edit port as described above
4. Notice that it works now

Expected Behavior

Port should be set correctly.

Additionally, even if I manually change the port in the configuration file, after restarting the system, the port setting reverts to 0.

Only changing the configuration file permissions to read-only helped.
