My ESXi disconnects from my vCenter

[jrgalleg]

Hello,

I have one ESXi 6.0U3 (5050593) and my vCenter is 6.0U3h (9313458)

If I connect my ESXi to my vCenter using the IP everything it´s ok... But if I connect my ESXi to my vCenter using the hostname (not FQDN) apparently connects but after more or less 60 second disconnects from the vCenter.

What´s the issue?

Thanks

Hello,

Have you Firewall beetwen your vCenter and your DNS server ?

Your DNS server are correct in vCenter ?

Do you have vRLI or something monitoring your logging? What does the vCenter & Host logs look like in the time range when it disconnects? Have you tried moving the Host to another Network port or even another Switch? There could be Network collisions or dropped packets or something causing it to drop.

... using the hostname (not FQDN)  ...

I've never done it this way myself. I either used the IP address, or the FQDN.

Anyway, it looks like the vCenter Server cannot resolve the host's name (or vice versa). What I could think of, is is either a non-working name resolution, caused by e.g. an incorrect DNS server entry, or a missing search domain.

seems like communication problem -- dns server  to  vcenter and esxi host. best option is add the esxi host in local host file  C:\Windows\System32\drivers\etc\host file or appliance vi /etc/hosts.
