I'm facing challenge to connect esxi host to vcenter, which was working previously after changing vmkernel port for management. since than ESXi not responding in vCenter.
I did some troubleshooting and found some wired issue in esxi 7 that can be interesting for all of you.
Note:- vCenter and ESXi is in same vlan and same subnet.
vpxa service is running and listen on port 902 -- but not able to connect in vcenter , esxi host is reachable from vcenter.
ssh service is running and listen on port 22----but not able to access esxi over ssh.
hostd service is running and listen on port 443-- able to access esxi UI .
I ran nmap scan to verify open ports in esxi and found 443/tcp is open but 22 and 902 did not come in nmap scan while services are running fine.
also tried to check with telnet that also not connecting .
i have attached screenshot for quick understanding .
Please check and suggest how can i fix it.
Thanks in advance.
Is this the only ESXi host having these issues? Did you restart the ESXi host already? If they are in the same VLAN (ESXi/vCenter) there is not much that can go wrong unless you have firewall services configured on the ESXi host.
Yes, There are two esxi but facing issue with one host only.
No As It is running in production environment only i have restarted management services not host.
I have disabled host firewall but issue is the same.
