Hello,

My browser return ERR_CONNECTION_RESET when I try to access web UI with DNS like "proxmox", the hostname.
I can access to web UI with ip without problem but not with DNS.

I have nothing in the logs with :
tail -f /var/log/* /var/log/*/*

And I see the request with tcpdump.

Someone have an idea ?

Thank you
 
are you sure that DNS points to the same IP? Are you adding port to the URL? Can you use command line to ping the hostname and then show https request? What OS is your client?
From PVE shell does this work:
curl -ks https://localhost:8006
curl -ks https://proxmox_ip:8006
curl -ks https://"proxmox":8006

Yes for everything. I was seeing the request packets with tcpdump. Strangely it works since a reboot.

Thank anyway
 
From the client :
curl -k https://proxmox:8006/ : ok
With other browser : ok
With chrome : not ok
I try to desactivate kaspersky, clear cache and private browsing but nothing with chrome.
I try to compare request header, it's the same except "Sec-Fetch-Site" :
same-origin for 10.1.0.20:8006
none for proxmox:8006

I don't understand...

ok, so its not a network wide issue. Its a chrome specific problem that you are experience just with a local dns name. I think its safe to say that its not a proxmox issue...
Try from a different workstation. Spin up a VM , run chrome there. Examine developer tools in chrome.
Good luck
