Hi,

I have changed the default hostname provided by my ISP. Maybe this is the problem?

I have regenerated the SSL,
pvecm updatecerts --force

but problem is still:

Any idea about how to solve?

Thanks.

What browser/OS doe you use to access the GUI?

 

[jmjosebest]

Thanks Dietmar for your reply.

I use by default chrome in Win7.
But also tested with Firefox and IE.

I read about a local problem with Java version, but, I have other Proxmox servers and I can connect without problem. Anyway, also I have tested to reinstall Java and the issue is still.

In the console screen I see:
Status: Connecting to pveabs1.xxx.xxx, port 5900
network error: could not connect to server: pveabs1.xxx.xxx:5900


In the syslog I get:

Jul 30 17:54:09 proxmox pvedaemon[2185]: starting vnc proxy UPID:proxmox:00000889:0000F6E6:5016AE21:vncproxy:100:root@pam:

I try

telnet hostname 5900

and I get:

telnet: connect to address x.x.x.x: Connection timed out

Iptables are empty on the server. Trying to disable my firewall... and same issue.

 

[jmjosebest]

Solved!!, was a perimetral firewall in the datacenter. Need to open 5900 port.
Regards.
