Ubuntu 24.04 container networking problem on Proxmox 8.2.2

[mdalacu]

Hi, i am scratching my head for a day now with a weird problem.
I am very new pro Proxmox 8.2.2 (like a day) so bare with me.
I have tried to install ubuntu 24.04 as a container without success (using the latest template 2).
Then i have installed and configured ubuntu 23.10 without a problem. I have updated proxmox to the latest debs using the repo.
I have installed xfce desktop envirorment and xrdp. All was working fine, internet included.
The net is static bridged to the main proxmox adaptor using a different ip.
The i create a snapshot so i can revert to it easily.
I have started the upgrade witch crashed because of snapd (firefox, thunderbird..etc)
I have reverted to the snapshot, uninstalled thunderbird snapd and firefox and i have retried the upgrade to noble.
Everything went fine and it booted ubuntu 24.04.
Now, the weird stuff begins:
I can connect to it on 3389 and login int it without a problem.
If i open a terminal i have internet access..wen using apt, wget, ping etc.

In firefox, chrome and opera i have the error: ERR_INTERNET_DICONNECTED

Please help!!!

Ideas? Can you access local IP's (with IP address number) from browser? Can you access a Public Web Site with it's IP address from browser, (try 8.8.8.8 maybe).

Hi! Thanks for getting into this mubo jumbo...
No, i can't..Which is strange because in the same XRDP session using a grafical termnal running elinks it works!
N.B. No proxy is defined anywere

Firstly the browser should probably be trying to access http.... not https....... for those local IPs.

Secondly I would try an apt-get update & then an apt-get upgrade in the Ubuntu VM, maybe then the browser(s) will start working.
