Unfortunately Davx5 is broken if you use a firewall to block google calling home to the mothership
Thank you for pointing out Davx blindly follows NET_CAPABILITY... which calls home. I avoid data mining apps but don't have a firewall to protect from these cases, may I ask what you recommend?
I use AFWall. I dont trust the VPN firewall solutions because that would easily lead to accidental leaks.
Davx5 from Fdroid has no dependency on Google
You're right. It has a bug.
I use Rethink to block 90% of my traffic, including all system processes on my LineageOS. DAVx⁵ works like a charm for me.
Obviously you're not blocking google.
I went trough 5 days of Rethink logs to confirm. Not a single call to a Google domain was allowed. DAVx5 works great.
Another user posted that Davx5 from Fdroid has no dependency on Google. Maybe you're using the Playstore version? I don't even have GApps to install the playstore.
the logs are coming from your OS, not the app
Update: For your info, this known bug's discussion is here:
If you're using the latest version of Davxx5 and your syncing is not broken, then you are not blocking your system from constantly pinging Google.
I'm sorry you're experiencing this bug. I'm not however. I even checked my pi-hole: the only access to connectivitycheck.gstatic.com comes from my wife's phone, which isn't hardened.
I vaguely remember doing some fiddling to the captive portal setting years ago. I probably found a way to disable the check altogether.
Its a bug. Its not closed source dependency. It requires your device to make a call to a Google domain.
If your phone doesn't call home to that domain, DAVx5 refuses to connect to the internet. Its a known bug.

I'm using the one on F-Droid. I do not have gapps on my devices.
What they say "no dependency on Google" they mean no proprietary blobs. That's true. The calls home to Google to check for internet activity are made by open-source software baked-into AOSP.
If you use a firewall to block these calls, then the OS says that you don't have internet connection and Davxx5 is dumb enough to take that as fact and refuses to sync. This is a known bug.
On custom roms like grapheneos you can change the domain it connects to. Om grapheneos it defaults to servers hosted by grapheneos.
That probably explains it. So your firewall isn't setup to block your phone from phoning home to the Graphene mothership then..
