Unable to connect to XMC 8.1 with Java-concoles

[Ilya_Semenov]

Hello, team,

I've done a clean install of XMC, PV and NAC - everyting version 8.1 - under ESXi. XMC, PV, NAC and client computers are in the same VLAN. There are no firewalls between them. Everything is sinchronyzed with single NTP. All DNS recored were created. I can ping NAC from XMC and vice versa.

I've added to XMC PV and NAC - they both are green.

The problem is I can't connect with Java-consoles to XMC. "Unable to connect to management server". Nothing in XMC's log, the same in NAC's. I've turned it to verbose.

What most likely could be the problem? I hope this is 8.1 version specific issue...

Please, help!

Ilya

Is your Java up to date? I seem to remember all my Java consoles failing following an XMC upgrade, and it was an update to my Java that fixed it.

Try Java 8 or 9 instead? I know with Java 9 it didn't work straight away (can't remember if it was an XMC or Java minor upgrade that fixed it, I was trying it for HiDPI support).

It's 10th Java. The latest.
