@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.

Hi, I looked all throughout the forum for a way to use AdGuard with OpenVPN and I am a noob so I dont understand what IP im supposed to use? Is it the one i installed Cloudron on? A different one?

I got the settings button to show up on OpenVPN but when i put in the the server ip that both OpenVPN and Adguard are hosted on, i cannot connect to anything.

What am i doing wrong?

Thanks.

@Jenova said in OpenVPN with Adguard:

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 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.

@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.

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.

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.

Edited my response.

@Jenova said in OpenVPN with Adguard:

DNS Servers . . . . . . . . . . . : 10.8.0.1

So, the above line tells us that it got the internal DNS server correctly. So, far so good!

Next step: Disconnect from VPN. Then, go to the OpenVPN settings and put '8.8.8.8' as the DNS server. (https://docs.cloudron.io/apps/openvpn/#custom-dns-server) . Now, connect again.

Are you able to connect to VPN or is it that you are able to connect to VPN but unable to connect to any website? If you run ipconfig /all again now like before, what is the output ? (I am expecting the DNS Severs to be 8.8.8.8).

@Jenova thanks.

With the default OpenVPN app settings, please connect from Windows. After connecting, can you please check what it says the DNS server is? https://askleo.com/find-dns-server-used-pc/ says if you run ipconfig /all , it will display the DNS servers. Can you post what that command returns?

Also, I am not a Windows expert. TBH, I haven't even used Windows in many years, but I will try my best and let's see how far we get
