Have you tried this?
I answered at the bottom of my post no. 15.
I tried without success.
What happens if you ping 140.82.121.4 from the HA host?
What happens if you ping github.com from the HA host?
“login” works
and
curl GitHub - hassio-addons/repository: Home Assistant Community Add-ons works too.
No errors but a lot of stuff.
@WallyR
ping 140.82.121.4 brings “is alive!”
ping github.com brings “is alive!”
Could you try to install HAOS under Hyper-V in a Windows machine, then check if the add-on store issue persists?
Unfortunately I do not have a free bare metal machine to try that.
Would VirtualBox on Windows be an alternative ?
Or do I have to expect new issues with that ?
You can always check if the add-on store is visible there.
Unbelievable: on Virtualbox installed on a bare metal Windows 11 system it works like a charm. So “my” problem seems to lay on Proxmox.
How may this learning help me to identify the Proxmox issue ?
At least you now know it is not something on your network.
I can’t help with your proxmox issue, I used tteck’s script and I have no problems with the add-on store.
I found the reason !
In Proxmox the MTU size of the vmbr was set to 1464. After removing this entry the store was not empty anymore.
Thanks a lot for trying to help me.

Just for future reference Hyper-V is part of Windows 10 and 11 and can be easily enabled in control panel → programs & features → turn windows features on/off → Hyper-V (it is installed as a type 2 hypervisor).
I was going to ask you to check Proxmox against my guide but I thought this would be too much to ask.
Glad you identified the issue.
Well, of course I checked your guide by installing my current system getting along with it. It works fine and covers all important aspects. The reason why I struggled was in my PVE configuration.
Almost.
Hyper-V is not part of the Windows 10 Home version and it is not officially available for that version at all.
There might be some tricky ways to install it, but it is not for a normal user to do.
And it looks like the Windows 11 Home might not support it either.
