Jenkins Poll SCM Issue

Question

Im trying to do something extremely simple with Jenkins. That activates a pipeline when a change to my repo is detected. I have just 2 settings (shown below).

However, any change to the repo And waiting the required polling time it does not trigger the pipeline?

Am i doing something daft here?

EDITS:

• This is in a docker container. The containers time is UTC and the host is BST based. I have updated the TZ at container run time via -e JAVA_OPTS=-Duser.timezone=Europe/London.
• running a tcpdump on the container I see not traffic (https) outbound to github.
• Poll Log added below.

Consider using the basic Git feature, vs the GutHub project feature. I have always had better luck with generic features vs features specific to a particular service provider (GitHub, Bitbucket, etc.) See image below.
