Jenkins ver. 2.190.3 installed on windows server 2016
ec2 plugin version 1.46.1
Jenkins log shows this error when it is trying to provision a windows jenkins slave:

I tried changing various configuration settings but did not manage to get around this error.
Any clues what can I do?
thank you
Later edit:
After restarting jenkins now, in the logs I can see this error which seems very much related:
