问题
EDIT:
I found out that, on UBUNTU 16.0.4 the SCM Service is working fine and I do not face the problem. However, I'm having this problem on Ubuntu 18.0.4.
Any idea how can I check the SCM service logs?
Problem:
- Jenkins is not able to Poll for changes in the git repo. However, if manually triggered, the recent changes are fetched and then the job is built.
Jenkins Config:
- Jenkins master machine is in AWS cloud behind a load balancer.
- All slaves are in my local network which can connect to Jenkins Master and execute jobs as per Master's command.
Solutions tried so far:
- I suspected some problem with the local firewall and tried connecting the node to a network which did not have any firewall. Still, this did not work.
- I tried deleting the existing nodes and adding them freshly. Still, it did not work.
- I tried with Bitbucket branch source plugin since all our code is on Bitbucket cloud.
What I'm expecting to solve this:
- If anyone has faced this issue before, please let me know how to resolve this.
Else, I want to know is there any way that I can see the polling logs at the system level.
Please note: Not in the Jenkins (which I know). Please note, I do not want to see the logs at https://mydomain/jobs/SCMpollLog as they do print only after polling is triggered and then polling is a success or not. I want to know the reason behind why polling is not occurring.
Pleaes let me know if you need any additional info.

As a workaround, I would recommend you using the git hook: it will create an event once the repository has been updated and push it to Jenkins.
