For some reason I cannot add my servers to VM Explorer. It keeps giving me the error of

  ESXi SSH/SCP Error: There was a problem while connecting to hostname.domain:22

Now this is on vSphere 6.7 U3, the hosts are on ESXI 6.7 U3 Build 17167734

VM Explorer is on 7.1.3

I can use Putty and WinSCP to connect to the hosts fine.

Im thinking its on the VMX Explorer side but I cannot tell why and the error does not seem to give much info.

Is there any logs that I can look at to try to see why
