VRMC Connection Problem

Jump to solution

Hello,

i had a problem with a VRMC Connection.

when open VRMC to VM there hosted on my new Esxi-Server i get a black screen and message "Verbindungsfehler"  ("Connection Error")

VMRC Connection to other Machines there are hostet at a other Host works .

All Hosts are mangend with the same vCenter. (V6.7)

I update the VRMC from V11 to V12, but i get the same failure

I compare the VRMC Logs with a VRMC Connection on a other Esxi Server.

This are the different:

Hello,

we are found the failure.

The VRMC Client open a connection to the Host, not only to the vCenter.

We allowed in the Firewall the Host IP.

Now it works

 

Thanks
