2.3 upgrade to 3.0 ... web gui won't display but full html is being sent by server

[joevsthevolcano]

Hello,

I upgraded from 2.3 to 3.0 using the proxmox provided script and had no problems. That is, however, until I realized that the web GUI is no longer rendering. I can see all the HTML if I view source.

There are no errors in my daemon.log

I looked through the lengthy upgrade log and there wasn't anything that stuck out as indicative of this problem.

I have tried using Chrome, Opera, and Firefox on both Windows and *nix machines.

Is there a way to reinstall just the web interface?

pls post the output of 'pveversion -v'

did you reload the browser page, empty cache?

Yup, I emptied browser cache as well as hard reload. I even installed firefox and chromium on a new ubuntu to make sure it wasn't a caching issue.

try restarting pve-cluster and pveproxy (= webserver).

root@proxmox-6-175:~# service pve-cluster restart
Restarting pve cluster filesystem: pve-cluster.

root@proxmox-6-175:~# service pveproxy restart
Restarting PVE API Proxy Server: pveproxy.
root@proxmox-6-175:~#

Done but no change. I tailed the daemon.log during the two restarts:

service pve-cluster restart

I have attached a txt file of the HTML being sent to the browser (but not rendering). I'm not a JS guy so I don't even know where to start debugging that.

Also try to restart service "pvedaemon" (after "pve-cluster)

I tried restarting pvedaemon but no change. I have, however, discovered something really strange.

I have however partially figured out the culprit. All of the different browsers and computers I was trying this on connect to the proxmox server via openvpn. If I use the public IP of the proxmox server, so the traffic doesn't go over the VPN, the GUI loads fine. I'm not getting any errors though and I never had a problem with this under proxmox 2x. This only started happening when I upgraded to v3. I am going to guess that the change from apache may may not work well with a UDP vpn and I plan on testing this by swapping to TCP later tonight once the office has cleared out.
