Hey Forum,
when I was using Nextcloud 11.0.3. running php 5.x and mysql… (on a pi 1, of course) with a let’s encrypt ssl-certificate i had no problems to access any of my calendars from thunderbird.
then I recently ungraded to NC 12.0.0 (on a pi 3) and am running php 7.0.19, mysql 10.1.23 with a new let’s encrypted ssl-certificate (aiming, of course, to the same URL) and until then I can’t establish any working connection from thunderbird to any of my calendars.
I still can access them via outlook and the loveable outlook-caldav addon as well as via android -app ICal-Import/Export Pro 3.1
BTW: I’m running Thunderbird (52.2.1) (32bit) on a Windows 7 SP1 (64) Pro-machine. With no problems so far.
hints, suggestions anyone?
