@domubpkm hej thank you for your reply!
I tried mitubo again it works.
Before i got error codes when trying to watch or download. The last days a few things improved on my fp4! Still figuring out what changed.
All in all its gotten more smoothe for sure.
So thank you for reminding me to try mitubo again 😉

A command I've found which changes the authentication method from the command line is:

/usr/share/ofono/scripts/set-context-property 1 AuthenticationMethod pap

The number may vary depending on which order the APNs are displayed in /usr/share/ofono/scripts/list-contexts. I found this on https://docs.droidian.org/info/apn/

@hilbert a little late to the party, but you are right the other variables should not impact your sync. I think the "config name" can be important, if you used special characters it could be problematic, but other than that they all are phone related.If you still have problems with carddav sync, i wrote a script which setup these things with automated sync (systemd instead of cron), take a look here : https://forums.ubports.com/topic/10127/contacts-carddav-automatic-setup-and-sync-through-this-script
(hoping you already solved this issue 🙂 )
