Hi, i just wanted to add, that this problem exists for us as well with just SOGo Calendars, accessed via https, using TB 3.1.x.
SOGo 1.3.1, nightly connector, std lightning or inverse lightning nightly. So using 3.0.x TB is just a workaround, the problem with 3.1.x (and https? did not try with plain http) still exists. Regards, C. Stritt
