OpenVPN with Adguard

@Jenova said in OpenVPN with Adguard:

DNS Servers . . . . . . . . . . . : 8.8.8.8

Ah nice, it does get the configuration correctly!

Its funny cuz now i can connect.

One thing to know is that these days browsers also have all sorts of DNS caching going on. So, best to restart browser to make sure we are testing things afresh.

It's funny cuz now i can connect. I actually uninstalled Edge and all related software to Edge and installed Brave instead and i can connect to literally everything. I'm going to try my server again and see if i can connect now.
Edit: As expected, i cant connect.

Can you tell me what happened between being able to connect initially and not being able to later?

In the output where you can't connect, the DNS server is wrong 23.237.137.11 .

Also, out of curiosity, maybe you can also try to connect from your phone and see if you are able to connect. This will help identify if this is some openvpn client issue or some server side issue. I suspect something with Windows OpenVPN client.

I added the IP address of where my AdGuard is hosted.

23.237.137.11 is the ip of which both Adguard and OpenVPN are hosted at so i assumed it would be what i would put in OpenVPN's DNS.

I will try tho and report back

Edit: It works flawlessly on my phone.

@Jenova I guess that's good news and bad news

I have to leave you on your own here, since I have no clue how Windows DNS works. See http://woshub.com/dns-resolution-via-vpn-not-working-windows/ and https://serverfault.com/questions/356115/vpn-connection-causes-dns-to-use-wrong-dns-server for maybe some ideas.

Unfortunate but I'll ask on Adguard and OpenVPN forums then. Thanks for your time.

@Jenova it happen to me when I didn't add my secondary Server IP(Adguard) on primary vpn server with cloudron.

So I went to my adguard server and I had go to setting on webgui->setting->dns-> allow client so I added primary IP on there and now it working.

I don't have a secondary IP. The VPS with which OpenVPN is hosted on is also the one Adguard is hosted on. There is only one IP for that server.

Do you think I should buy another VPS, install Cloudron on it and install either my VPN or Adguard on it and try with that?

Yes, I think this will work (because from our experiments using 8.8.8.8 clearly worked).

I'll do this. OpenVPN forums where of no help at all.

@Jenova
I downloaded the default openvpn file from my cloudron vpn app (I did not change any settings in the app) and then added these 3 lines to the ovpn file to force my dns server...

dhcp-option DNS ~IP OF MY SERVER~
register-dns
block-outside-dns

Unfortunately that didn't help. Thank you for trying though. I already bought the new VPS too so we shall see if this works. Cloudron just got installed so I'm going to attempt to install OpenVPN first and if that doesn't work, ill install AdGuard Home

Having a secondary server with Adguard on it works. I assume some configuration on the original Adguard server broke because the OpenVPN on the secondary server still couldn't connect with my main server Adguard.

Thanks guys for all the help, this can be marked as resolved.

Good to know these! Apparently, these are Windows only directives - https://iflorian.com/openvpn-block-outside-ds/
