I’m working on a CircleCi job running a configuration on an EC2 instance. The problem is that the ansible could not run the configuration and is still running in a loop on this error

I have already added my key pair to the Circle project settings, obtained the fingerprints and added it to the job configuration ([bla:bla…]).
I can connect to the Ec2 instance using ssh without any problems.

Any help or suggestions would be greatly appreciated.
