CalDAV Connection fails (android)

[drtsdgdj]

With the android version 10.0.11 I still get the following error, when trying to link the posteo calendar:

CalDav: Request failed because of a client side network error

I also tried several combinations with the Base-URL: https://posteo.de:8443/
as listed in the comments above, but no success. There is no whitelisting option in the posteo account settings.
Also tried the full link as with the desktop version. With the Linux desktop version 10.0.11 (snap) I can connect with the following settings:
Base URL: https://posteo.de:8443/calendars//default
Name:
Username without @posteo.de

Thank you very much for opening up this issue! I am currently a bit overwhelmed by the many requests that arrive each week, so please forgive me, if I fail to respond personally. I am still very likely to at least skim read your request and I'll probably try to fix all (real) bugs if possible and I will likely review every single PR being made (please, give me a heads up if you intent to do so) and I will try to work on popular requests (please upvote via thumbs up on the original issue) whenever possible, but trying to respond to every single issue over the last years has been kind of draining and I need to adjust my approach for this project to remain fun for me and to make any progress with actually coding new stuff. Thanks for your understanding!

There is a new android app in the process of being roled out and that might fix your issue.
