Cannot connect to Vcenter Error: Cannot complete login due to an incorrect user name or password.

[olivierBTIreland]

Hello after upgrading to Vsphere 6.5 the script stopped working.
I noticed the script running in my customers environment for about 3 years was outdated and got the latest version from the report

Now when I execute as below

vmwarevSphereHealthCheck.pl --server 10.10.10.10 --username ABC\myname --password Mypassword123--type vcenter --datacenter City-West --email yes

the result is

Error: Cannot complete login due to an incorrect user name or password.

I tried it against two different vcenters and got the same error about incorrect password

Is there a catch I didn't get with the input parameters ?

Thanks a million
Olivier
