Multibranch not working


I am running into an interesting issue. When creating a multibranch project for Instavote I am running into this issue. Checking branches...

Getting remote branches...
Checking branch main

Getting remote pull requests...

I think the issue is due to the file not being able to find the branches but I am unsure.
I was able to validate connecting to github successfully. Jenkinsfile is in the worker/jenkinsfile path.

    We worked this issue on the Office Hours today:

    1.- "Could not fetch branches from source" may mean that the source is incorrect in the pipeline, but it seems not to be the case. It also can be a connection issue with the repo.
    2.- During the session, there was a problem with accessing the Jenkins server, so it may be a network issue to access it.
    3.- It seems some elements were moved from the local directory (that holds the Jenkinsfile), so in that case something will be broken for sure.
    4.- Jhon will try again with a fresh installation and update this post later.
