Webdav Calendar certificate check fails with IPv6
Hi,
I am using Thunderbird 78.7.1 (64bit) under Ubuntu. I would like to sync my WebDAV calendar with Thunderbird Calendar. I have configured the calendar via its IPv6 address. In the calendar config, I enter the address: https://[2a02:908:1341:xxxx:xxx:xxxx:xxxx:xxxf]:5006/path/path/ ("xxxx" and "path" being replacements for privacy reasons).
There is an exclamation mark behind the calendar name in the calendar overview taht shows the error message when hovering over it: "The calendar xyz is currently not available." (translated from German "Der Kalender xyz ist momentan nicht verfügbar").
When clicking on "Kalender synchronisieren" (sync calendar), I get the attached screenshots: Nothing happens if I click on "Sicherheits-Ausnahmeregel bestätigen" (confirm security exception rule) or "Zertifikat herunterladen" (download certificate). The button is pressed and greyed out, but no further action happens. I can click on "cancel" (Abbrechen).
Port 5006 is reachable via telnet and its IPV6 address.
My questions: Is it allowed to enter an IPv6 address in the calendar config? What may be the reason for dealing with the certificate, having no reaction of Thunderbird?
Thanks,
Superwallah

Now it works: Leaving out the port (using 443) in the security exceptions, it worked. And: I had to add the security exception manually in the settings. I was not able to press the offered button directly. The IPV6 address in the exceptions is still shown without brackets which is confusing.
But still: There is a bug around this case......

Looks like the cert expired.

Of course, you were right. I thought I had a few more days. Unfortunately, also with the renewed Let's encrypt certificate (valid until 12.7.2021), I get exactly the same errors.
Any further ideas?
Can you create an exception when prompted? https://support.mozilla.org/kb/add-security-exception
As I wrote, adding the exception via pressing the button (see screenshot) is not possible. When I press the button, it is greyed out, but nothing happens anymore. The only option I have is to click cancel. This, at least, is a bug.
If I go to Edit->Settings->Security->certificates->Server->Add exception and add the URL without the path there (so https://[2a02:908:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx]:5006), then I get the same warning screen. But here the button "add security exception" can be pressed. A line in the table of the "server" tab in the certificates settings is added (with correct expiration date). ...but with the Server address as IPv6 address without the brackets! I looks then like "2a02:908:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:5006". Can Thunderbird then distinguish between the IPv6 colons and the port colon??? Is that a bug?
When I then go to "sync calendar", I get the same security warning as before.
I know that this is not the straitforward use case, using an IPv6 address. But it should work, shouldn't it?
