thanks for your replies. I even set everything to manually sync only but there is no improvement.
Yes Blokada is an Android app but the issue also manifests on the nginx logs…
@rfc2822 : what do you mean by local changes? I use the offical version and SimpleCalendar for Calendar, Open Tasks for tasks and the stock Contacts app…
One possible issue i found was that I only had an Account for addressbook sync (only sync item: “Contacts”) in Settings>Account for Davx5 and now, after going back and forth between this and davx5 app I have another davx account with three sync items: “Address books”, “Calendar”, and “Tasks”.
I remember that Davx created two accounts but it seems that the second one includes all sync items…
