[voitsykh]

I have vSphere 6. And I want connect one esxi how thoung Internet. I opened ports 443 and 902 at the router. ESXi connecting. But after ~ 1 minutes - disconnected. I push button Connect and it connected aganin. But also 1 minutes left and disconnected...What it can be?

You have opened 902 UDP too or just 902 TCP ? See: VMware KB: ESXi/ESX host disconnects from vCenter Server 60 seconds after connecting

Yes, it is may situation (but no 60 sec, ~45 sec).

I can use the vSphere Client to successfully connect to the ESXi/ESX host directly.

I have opened 443 TCP, 902 TCP&UDP.

Any other idea?

I installed update 2 on vCenter and look like it's help.

Hope it will work without disconnete always
