Connection Refused by ProxMox

[Craig Lowe]

I have had an issue ever since I installed ProxMox, whereby it will refuse all connections from a specific IP address and I cannot work out why it is happening.

If I restart the server and connect to ProxMox via the WebUI or SSH it will allow the connection. If I go back to it later and try to connect from the same device it will refuse the connection. The only way I can get it to accept the connection is to change the IP address of the device, which it will then instantly allow the device to connect again, until a few hours later when I attempt to reconnect and it will again refuse the connection. I have read a couple of times that clearing browser cache will fix the issue but that doesn't work. As it works when I change the devices IP address I am assuming it is a different issue.

Many Thanks,
Craig.

I have the exact same issue, has this been resolved?

Ouch, I actually have to say it was my stupidity. I don't know how, I don't know why, I forgot to add port 8006 to my machine.
Sorry for the confusion.

I'm having the same problem and the only coincidence I can see is that it happened to me today for the first time and today I've installed a second Proxmox machine in the same network.

Could those interfere somehow? I haven't set up any cluster whatsoever, the second machine has just freshly booted up.

curl https://192.168.1.5/ -v

Reboot does not help in my case.
