RemoteDisconnected('Remote end closed connection without response')

[immo]

HI,

I do have a python script which use pyproxmox. This script shows quite often an
ConnectionError(ProtocolError('Connection aborted.', RemoteDisconnected('Remote end closed connection without response',)),)
Error. And yes we do have GUI connection abort issues too.
Is there any know limitations for VMs and Clusterhosts ?
What should I provide for a deeper analysis. I woulndt bring this down to the pyproxmox api...

hi,

do you also get aborted connections with SSH? if you do it might be a networking issue.

if SSH works fine, then it could be PVE specific. you can provide some information about your setup: (remove sensitive information such as public IP)

* pveversion -v

* ip a

*ip r

* cat /etc/hosts

* anything interesting going on in the logs while these disconnects happen?

* is firewall in use? if yes, what rules are active?
