Hi all
we have an strange problem,
in VCSA 6 , many of our esxi 6 hosts which have valid IP addresses become "not responding" and after disconnect and reconnect, we get the error say: "request time out"
I tried most of solutions like, restaring esxi host or restaring vcsa, regenerating ssl certificare on host, checking 902 and 443 ports on both sides (either host or vcenter) they are open and can also both sides can ping each other. (even disabling firewall totally on host). but didn't resolved. there are only 2 points, when we change IP address of the esxi host with another ip in same subnet, it will add successfully to vcenter but after a few days it became like the previous IP and not responding, same problem... and the second point is when we try to add the problematic host to a secondary vcsa, it will add without problem. my doubt is that main problem should exist on our main VCSA and if some logs are causing problem which ones are safe to delete on vcsa? or anyone can kindly help us with this issue? thanks in advandce
