Calendar Sync via Caldav to Thunderbird (Lightning) stopped working
today all over sudden the sync via Caldav to Thunderbird (Lightning and Caldav Plugin) stopped working. I know a lot of people here might say the same "I have not changed anything" ;-) but I really didn't change one piece on my Zimbra for the last weeks. I use the following zimbra version
I use a URL like this to access caldav: https://mydomain.tld:email@example.com/Calendar
su - zimbra
[zimbra@webmail1 ~]$ zmcontrol -v
Release 8.0.6_GA_5922.RHEL6_64_20131203103705 RHEL6_64 FOSS edition.
Port 4433 is forwarded to zimbra's LAN IP on port 443. But I also tried with https://firstname.lastname@example.org/Calendar
Same effect: Thunderbird cannot access the calendar. The strange thing is that TB does not even ask for the password. I deleted the stored password from TBs password-manager but does not help. TB does not ask for a password. I deleted the calendar from TB, removed and reinstalled the two plugins (lightning and caldav) and at the end even re-installed Thunderbird but all does not help.
But when I call one of the URLs above in the browser I get asked for a password as expected and I get the txt file with the calendar definition stuff. I use TB 24.5.0 on fedora 20
Thanks a lot for any input as I'm running out of ideas :-)
[SOLVED]: Was admins aka my fault ;-)
Finally I got it :-) But not before installing twice Fedora as VM again. Both times TB could not connect
Then I thought what I changed last week my other servers. Ups yes it created a new key and a new certificate and revoked the old. But did I replace the certificate on zimbra? Nope. I placed the new files on all my servers but forgot zimbra :D
After rolling out the new cert on zimbra and a short restart of services TB immediatly asked for a password.
I just wonder why not one browser complaint about the cert when I tried to access the caldav url with the browser. chrome and firefox asked for the password, no warnings about cert shown.
This time TB did right to cut the connection, but a more "speaking" error message would have saved me hours :-)
