1800527 - "Add Security Exception" dialog shown for every update of network calender -after upgrade to 102.4.2

Status: RESOLVED DUPLICATE of bug 1792470

(Calendar :: General, defect)

Description

[Johannes]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:104.0) Gecko/20100101 Firefox/104.0

Steps to reproduce:

I use two network calenders on the same server. A security exception for that server and port is stored in Thunderbird since years.
I upgraded from Thunderbird 78.14.0 to 102.4.2.

Actual results:

Now every minute - the configured update interval for these calenders - a dialog "Add Security Exception" is shown. Neither saving that exception nor canceling this dialog seems to make a difference, the calender can't be updated.

The error console shows (only messages for one calender pasted):
22:06:33.827 PROPFIND https://server:5009/share/Kalender/Kalender1/
22:06:34.083 Calendar: There has been an error reading data for calendar: Kalender1. However, this error is believed to be minor, so the program will attempt to continue. Error code: DAV_NOT_DAV. Description: The resource at https://server:5009/share/Kalender/Kalender1 is either not a DAV collection or not available CalCalendarManager.jsm:828
22:06:34.084 Calendar: There has been an error reading data for calendar: Kalender1. However, this error is believed to be minor, so the program will attempt to continue. Error code: READ_FAILED. Description: CalCalendarManager.jsm:828

Expected results:

The saved security exception gets used, and confirming a security exception is really saved.

I'd try re-subscribing to that calendar.

I can't subscribe to these calendars again. I get seven times the "Add Security Exception" dialog when clicking "Find Calendars" on the "Create New Calendar" dialog. After the last one it says:
"Could not find calendars at this location. Please check your settings."

Output of Error Console:
20:48:28.939 Calendar: [CalICSProvider] Could not detect calendar using method attemptHead - HTTP response status -1 CalICSProvider.jsm:94
20:48:29.010 Calendar: [CalDavProvider] Could not detect calendar using method attemptLocation - HTTP response status -1 CalDavProvider.jsm:99

Manually removing the corresponding line from the file cert_override.txt (when Thunderbird isn't running) doesn't help either.
