I have a shared library in my Jenkins server that I call "common-pipelines". From within my Jenkinsfile, I will call for a specific tagged version of the common-pipelines shared library to be loaded like this:

@Library('common-pipelines@v9.4.4') _ 

I was just alerted that the pipelines are erroring with the following message:

Please make sure you have the correct access rights
and the repository exists. 

However, we aren't sure what changed. After much sanity checking, I was able to determine that this works normally if I call for a branch name rather than a github release (git tag).

In other words, this works just fine:

 @Library('common-pipelines@myBranchName') _ 

I am running the latest plugins.
