Proxmox GUI Timeout

[John Blockyou]

I installed Proxmox 5.4 on a server today.
Everything was working correctly for several hours..
I entered my subscription key and then I updated Proxmox using ssh.
The updated were applied and I rebooted the server.
Now the web interface times out every five minutes (have to log back in) weather you are working with it or not.
I searched the net and found several things to try (date and time set, force server certificates to renew and more) but none worked. I found one person who said re-installing it fixed his server.
Anyone seen this or have any ideas where to look?
Thanks!

Update...
I went ahead and reinstalled proxmox.
Everything started working perfectly again.
I played around with the interface for about 45 minutes without being kicked off so I decided to do the updates again using the interface.
About halfway through the updates I was kicked off again.
When the updates were completed I rebooted the server.
When I logged back into the interface everything was working perfectly again.
I left the interface open for about 45 minutes and I wasn't kicked off.
I'm not sure whats going on, but Proxmox is working fine now.
