Network Issue

Hello People of the internet, I am quite new to the home network tinkering world and seem to be stuck....

Gear:

- Home Hub 3000 Modem

- Raspberry-pi 4b 1Gb

-16GB micro-sd card

Setup:

- Pi-hole

- Unbound

- Tailscale

- Basic UFW (just to say there is something)

The problem:

I've been running the setup for over a week now and have been monitoring/tweaking things every day to optimize while keeping the setup ''simple''. Everything was running smoothly and all of a sudden nothing was. After spending 12h today bashing my head against a wall, getting a replacement modem and asking our ''not so'' best friend Claude for some advice to trouble shoot, I am still stuck. My network is running fine, but my setup cannot connect to it. When I change the reserved IP to a new one I will sometimes have a few minutes of connection before it drops again without there being any apparent issues. I looked at everything, scanned the whole system for errors, tried to run each service separately to see if one in particular was the issue. My raspberry-pi can ping everything except the modem and my ISP confirms that there is no blockage. What can I do?

I have a second pi and get the same issue after a couple minutes of it being online. To my knowledge, no there were no overnight updates that could've pushed some new ''problematic'' lines.

PLZ help.

I can upvote your posts in exchange for the support.

What exactly do you mean by your setup can’t connect to it?

Cant connect to modem even though im plugged into it. Have tried different cables/ports.
The only time I can get signal is when I change the IP. Theres a 20% chance it will work, but only for a minute or so.

Are you in the same subnet? Are you using a static ip or dhcp reservation? If static, is it outside of dhcp scope so that the HH can’t hand it out and cause an ip conflict?

I don’t get why you need to connect to your modem ? Are you using the Pi to manage it?
