KVM not working for UCS-EN140N-M2

[SIMMN]

I have a brand new ISR4431 with UCS E EN140N module. I got the access to CIMC over network and status shows ok. But when I tried to launch KVM from CIMC, I got "network connection has been dropped."...

I did try to factory reset the module, but no difference...From java, it shows trying to connect to https://<CIMC-IP>:443/. I know for sure port 443 is allowed from my computer to CIMC. Does TCP port 2068 also needs to be opened between my computer and CIMC? Any other ports as well?

The CIMC version is 3.1(4.20170327095406) and BIOS version is UCSEN.1.5.0.3.  The java version on my computer is Version 8 Update 191.

Please advise.

Greetings.

2068 does need to be open.

I think 443 and 2068 would be your primary ports for getting vKVM to work.

Thanks,
