Unable to add Host to VCenter Server 6.5

[thhg]

My VCSA 6.5 is working well and I've added a number of hosts to it already

However, when I try to connect to 1 of my hosts (5.5 build 4722766), VCS takes a long time during "validating" and finally comes back with an error message :

"Cannot contact the specified host. Host may not be available ... etc

I AM able to connect to the host with a VSphere client and sort of manage it from there

I CAN connect to it with Putty and log in

I CAN connect to it with WinSCP and browse all the files

Can you attach vpxa.log from the host in question for review?

[thhg]

Log is attached

[daphnissov]

Are you attempting to add this host via FQDN or IP address?

[thhg]

IP address

[daphnissov]

Don't use IP address. Use FQDN instead. Always add hosts by FQDN.

[thhg]

Have always use IP addresses

Will give it FQDN a try

[thhg]

No Luck with FQDN - same message

[daphnissov]

Can you show the screenshot and full message you receive?

[thhg]

n capture

[daphnissov]

Have you tried to reboot the host? Sometimes that does clear things up.

[thhg]

Have rebooted both Host (to be added) and VCSA

No change

Just wondering if there's a log I should be looking at on the VCSA side

[daphnissov]

Yes, pull vpxd.log after trying to add the host. Record the time and state that here so logs can be more easily identified around that time.

seems like build issue. I had this issue once when I had higher build version of esxi host than mine vcenter version. and once I upgraded vcenter to the higher version than my esxi host. I was able to add host successfully as I usually we do.

Please check that out and let me know if that resolve your issue.
