Hello,
I had a working setup with carddav 3.0.3 plugin, syncing contacts from nextcloud (well actually, individual contacts where synced but not groups...)
So now contacts are not synced anymore, error message "internal server error", this is the(censored) log:
[07-Sep-2020 22:26:13 Europe/Berlin] Failed sending HTTP request: Header overflow

I removed all images from the contacts, the error is still the same and appears no matter what address I start typing in the compose window..#
help appreciated!
Also feel free to move this thread, I did not know if carddav is new api or not, so I put it here...
I cant install 4.0.0 because I cannot use composer at my hoster =(
