RACADM remote Issue: Unable to connect to RAC at specified IP address

Hey,

i tried to connect to a Dell PowerEdge R730 with RACADM remotely and got the error:
"Unable to connect to RAC at specified IP address" from one of my Hosts.

After some googleing i did not find a solution. I thougt it might be a firewall issue, so i used Wireshark from two hosts (1x working, 1x not working). I found out that RACADM uses TLS. With TLS 1.0 it does not work! So i enabled TLS 1.2 in the IE settings:
Internet Explorer SettingsIt worked successfully! Maybe some of you have the same issue. Hopefully it will help you, too!

Greetings:
Jonny
