kubernetes dashboard CrashLoopBackOff

Brand new to kubernetes, but managed to install kubernetes, ubuntu 20.04 LTS, but having issues with the dashboard. followed the procedure, using flannel as CNF.

The log states issues with connection to 10.96.0.1:443, but telnet seems to work? Any suggestion how to getting further ?
