vRealize 7.3 IaaS management agent fails

[aimeechristinef]

this is a new install of vRealize Automation 7.3 I am trying to install the management agent on the IaaS management server

fails with error validating appliance credentials. check the management site address is specified correctly. Underlying connection is closed. Unexpected error occurred.

The credentials are upper and lower case with numerics. special character is only a question mark.

I have redeployed and specified a new password. I can log into appliance with the password.

It imports the cert and then fails.

Any insight would be helpful..

Have you checked time synchronisation between all vRA nodes?

Yes and verified DNS

Interestingly, I can log into appliance with chrome but not IE.

I ensured TLS was enabled but IE states  incorrect credentials..
