## ISSUE ##

This is a New installation of Ivanti Patch for windows,

Once installed I was able to add 2 ESXI Vcenters, populate machine groups with discovered machines.

Came back a week later to add internet proxy details so I could start testing deployment and patching levels of the estate and I am met with:

I then removed one of the hosts and re-added and I get

Credentials have been confirmed to be valid and working,

Successful Connection from Ivanti VM to Host via SSH:

Can Ping the hosts successfully:

Can telnet (443) from Ivanti VM to hosts:

I have also completed a successful Refresh of all files.

Again the Credentials being used have already successfully added these hosts to Ivanti last week, and I can log in with these credentials to full admin level.

I have been unable to find any details of this issue anywhere else which has been successfully resolved.

Thanks Malachy
