You’re just making it worse better.

That image is not mine, it’s just for reference by the other user to show me where to look

Nothing, and it just reports 100% packet loss when I terminate the ping command.

this is the contents of the interfaces file

I don’t have anythiung seperated in to different VLANs, and i only use this single subnet. all other devices can ping outbound without issues.

no

No i haven’t split anything in to separate VLANs

It is set to my router IP

this is the output when i run curl httpS://google.com -vvv

this is the output of ip route.

192.168.68.1 is my router, 192.168.68.120 is the proxmox host

Nope, same result

Yes, adguard has access to internet

i have, it doesn’t work. I can ping my Adguard without issues though.

Nope, reboot doesn’t change anything

It’s pointing to the IP of my Adguard (located on a different machine)

It’s set to static, I also do that for anything that hosts something.

It won’t ping yahoo.com at all, it just reports 100% packet loss.

Edit: just realised that it won’t ping my gateway/router either. It’s pinging all other devices on my network just fine though.

This is what I’m thinking too, but I don’t know how to fix it.

I have, and it’s correct.

I use the KNX integration, which must be configured using yaml

This is probably because of the devs behind the integration though and not the fault of HA.

I have my all my cards and dashboards defined through GUI as well, you van make plenty sophisticated interfaces without YAML. A lot of tutorials are probably not up to date with what you can do though and use YAML.

None of my custom integrations are configured with YAML anymore, they’ve all moved to the GUI. Even a couple of my templates have been made directly in the GUI.

“Not a single line of YAML” is a bit hyperbole, but the only YAML I’ve got left in my setup are a handful of custom sensors, I haven’t checked if that can now be done from the GUI. It’s around 100 lines of YAML in total or something like that. But all the home automation stuff is done purely with GUI.

There has been huge improvements on what can be done from the GUI in the last few years since I started with HA.
