[SOLVED] New Install of PVE 4.4 - GUI output - "didn’t send any data"

[reinhardtjh]

Hello all. I just installed proxmox-ve_4.4-eb2d6f1e-2.iso onto an HP DL360. Installation seemed to go well but when I try to connect to the web GUI all I get is the message "xxx.xxx.xxx.xxx didn't send any data." "ERR_EMPTY_RESPONSE"

The only change I made was to change the ethernet device. The host has 6 ethernet ports and the install picked the wrong one. I modified /etc/network/interface and was able to connect. I can ssh to the system and ping in and out so the network interface is up. Outside sources can contact the web GUI, but it returns no data.

Various output:

I have stopped and started the pvproxy several times and run it in debug mode. Debug mode output is:

Previous lines from "curl -ik xxx.xxx.xxx.xxx:8006"

The result of the curl command from another host was:

system@vserver12:~$ curl -ik 172.25.40.11:8006
curl: (52) Empty reply from server

What do I look at next?

That is a really strange problem indeed. Normally, Chrome has problems with using a cached SSL connection on a server which changed SSL. Can you try to connect to your server in a private session in chrome? It normally fixes the problem if the certificate changed.

Hi LnxBil. I'm not sure what you mean by a "private session in chrome". Note that FireFox has the same response and when I try curl to just get the http output, it also says the response has no data. I don't think it's related to SSL.

I've also looked at the daemon.log and message.log and see nothing that looks unusual to me. But I'm a newbie to Proxmox so I may have missed it. I am not a newbie to Linux having played with it starting with Slackware in the mid 90's.

you have to use https, e.g.

curl -ik https://172.25.40.11:8006

and in the url in the browser you also have to specify it:

https://xxx.xxx.xxx.xxx:8006

I do. Well, I thought I did. How stupid of me.

Thanks Dominik!
