This doesn’t seem to be a Tor connection problem, but a CalDAV/CardDAV server problem. The connection to
oobee3hoosh2ocee.onion was sucessfully established, but Polipo on 127.0.0.1:8118 told DAVx⁵ that the
PROPFIND method is not implemented. So it’s either not implemented in the proxy or on the target server.
Can you have a look at your HTTP proxy logs?
Or can you use a working Orbot version until this problem is fixed in Orbot?
And so it is still may be great to have a Socks5 proxy support.
Which is not supported by native Android (there are no system settings for that), but okhttp seems to support it. So if you could send a merge request, I’ll merge it. The more difficult part would probably the UI and to store/use the settings, but it shouldn’t be that hard
