VPN: can't get WireGuard & AdGuard working

[imc67]

Before with only OpenVPN it did work, so it’s probably something with routing?

@imc67 good point, didn't realize. indeed, I did a quick test. even now, it works even now with OpenVPN. Just not in WireGuard.

Curiously, after I connect to WireGuard, I can ping just fine (ICMP) but cannot make DNS requests. Puzzling.

@girish dump the routes for both OVPN and WG connections?

Since one seems to have access to a local DNS while the other doesn't.
Otherwise it sounds like hair-pinning issue.

same here but definitely worked for some hours ...
DNS requests come to Adguard - ping, tracerout etc. don't work ...

mh...seems to be a firewall problem. When I allow "any IP" (TCP and UDP) on Hetzner-Firewall it works flawlessly... adding the Cloudron IP to the firewall doesn't work....Any idea anybody?

[girish]

@sponch so you are saying when you change the Hetzner firewall, AdGuard+WireGuard works?

[sponch]

just double checked... I thought it would...
probably used the wrong profile for my 1st test.
Sorry for the misinformation...

[girish]

For me, from the mobile, AdGuard works fine. Just not from the laptop (linux).

I pushed a fixed in the firewall for this. It's part of 8.2.3, you have to update Cloudron and hopefully that fixes this.

[sponch]

@girish That sounds great. I am on 8.2.1 and can't see any updates. Is there a way to force updating?

[sponch]

@girish YOU'RE GREAT! Wiregueard working now with Adguard after 8.2.3 Updater
