Just missed a meeting today because I accepted an event on Thunderbird this morning, that should have synced to Nextcloud, and then to my phone running a calendar app from ‘simplemobiletools’. Never made it. After I missed the meeting I didn’t see the event on nextcloud, then went to look at the event on thunderbird, and now lo and behold its on nextcloud, two hours after it was over. Cool. Still not on the phone.
Anyone have a solid calendar stack they like? I’d like to reliably get from emailed invite to alert on my phone.
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 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.
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…
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.
