@awfm9 Does the VPN maybe block Android’s “Is Internet connected?” test? Does your device say that it has no connectivity?
Since upgrade to Davdroid 0.9.0.4 my contacts don't synchronize with Radicale
since I upgraded to davdroid 0.9.0.4 my contacts don’t synchronize. Calendar and tasks have no problem.
I didn’t change anything on the server part which is Radicale 0.10
I added an e-mail information to a contact and I can see this information is not available on my server.
The Davdroid error log is visible here https://friendpaste.com/18wJtR5eC4i8fSA15oW7un
Thanks for your report. As you can see from the logs, Radicale returns a 500 Server Error. This is a problem of your server (assuming that the request is valid, and I don’t see anything invalid). Please report this to Radicale.
I use Radicale with DAVdroid 0.9.0.4 myself, and it works here.
