Can't connect to Adguard with my android phone

[Jenova]

Hello, I'll go into a little bit of background before I state the issue.

I was using HostWorld to use Cloudron on in the past, I then switched over to a free vps I got from a friend. We fell out, vps deleted, I went to switch back to HostWorld. Apparently my HostWorld vps doesn't support AVX, so I switched to IONOS.

Since getting this vps, I have had issues with adguard I didn't have in the past. I cannot connect using my android private DNS settings. Apparently nobody is able to connect either via the IP or the URL since I don't see any scanners in the logs. 0 hits for hours and hours.

I'm a n00b so anything dealing with ssh is gonna be very basic ("apt update" and "apt upgrade" are as far as my knowledge goes without needing my hand held).

Did I do something wrong? This is a fresh install, no configuration.

Sorry if this has been asked before. 🫠

@Jenova just to double check, are you using DoT to connect from Android - https://docs.cloudron.io/apps/adguard-home/#dot ? also, note that if you are using cloudflare, proxying must be disabled for the domain. This is because DoT uses port 853 which cloudflare will not proxy.

Also, make sure that tcp port 853 is reachable/open in firewall.

At first, I was using cloudflare, but I figured it was causing issues so I moved to ClouDNS. I'll look into the port to see if it's open, but like I said before this is a fresh install of both Cloudron and adguard. It used to work right out of the box. I've done several reinstalls of both Cloudron and adguard to make sure it wasn't just me

Edit: So apparently IONOS has its own firewall policy separate from the vps itself. I had to login to the dashboard and update the firewall to allow 853. It now works. Thank you for your patience. Never had a vps provider like this before. 🫠

Bumping this since updating to 8.0.3 it won't allow any connections

Edit: Saw a recent issue with IPv6. I'm removing it and rebooting. Will update when I'm done.

Edit 2: Nothing. Still not accepting connections. Now gonna try disabling whitelist.

Edit 3: ...works. strange.

[Jenova]

Unfortunately, this isn't a "solution" for me since I want to use the whitelist to keep the hackers and bots out.

Is there something I can do maybe to remedy this?

Not sure I understand. What whitelist are you referring to? Is this something inside AdGuard? Nothing really has changed in Cloudron 8 to affect behavior of AdGuard

The Allow list. It allows listed IPs to connect to the DNS and denies all others. It used to work but now that I've upgraded to 8, it won't allow my IP to connect, no matter if I use the exact one or use a range. The only time it works is when I remove all entries from it

@Jenova Oh, you mean the "Allowed clients" inside AdGuard Home ? If you use port 853 , then you are connecting directly to AdGuard and IP should be client IP.
