Solution simple: The firewall between me and the server was turned on yesterday, so that the port for the redirection got blocked:
If you check the dell manuals (support.dell.com) you'll find these default ports used by the iDRAC:
- 80 (HTTP)
- 443 (HTTPS)
- 22 (SSH)
- 23 (Telnet)
- 161(SNMP)
- 5900, 5901 (Console Redirection)
This is actually wrong. There is only 1 port for Console Redirection on an iDRAC6 and 1 port for HTTPS.

5900/5901 is right as per [1] port 5900 and 5901 are used:
DeleteKeyboard and Mouse Port Number
The network port number used for connecting to the Console Redirection Keyboard/Mouse option. This traffic is always encrypted. You may need to change this number if another program is using the default port. The default is 5900.
Video Port Number
The network port number used for connecting to the Console Redirection Screen service. You may need to change this setting if another program is using the default port. The default is 5901.
