  We are using SCM API PluginVersion676.v886669a_199a_a_ plugin in Jenkins 2.387.2 . With same plugin auto deployment is working sometime , not working maximum time. We have to restart Jenkins every time to make auto build work. Please suggest how to resolve the issue.

  Because the error doesn't happen every time, my first guess was that it could be caused by GitHub throttling, perhaps exacerbated by some change in git-plugin or git-client-plugin.  According to https://github.com/orgs/community/discussions/44515 though, GitHub doesn't "have any hard limits for clones".
  
  Are there any other messages above the "Error fetching remote repo"?

  SSH would normally use port 22, but Using SSH over the HTTPS port describes that GitHub allows SSH over port 443 too. Does your network have any middleboxes that might interfere with this connection as it is not actually HTTPS?

  girija_patra Hey, can you elaborate on what the problem behavior looks like? Do you see intermittent failures of jobs to build when this happens? It succeeds sometimes, but other times the job doesn't trigger?

  Hi Elijah, This issue got resolved after i updated Jenkins. With Jenkins 2.414.1 version it is working fine. No Issue with SCM/GitHub, Auto deployment is working fine.

  Hi Elijah, This pollSCM is worked fine for single branch. But it is not working when i configured another branch. Please find the problem details below.
  
   
  
  We have a single repo under which we have two branch, Branch A and Branch B. Both the branch have separate Jenkins file like Jenkinsfile1 and Jenkinsfile2. Both the jenkins file have
  
  triggers 
  {
              pollSCM 'H/5 * * * *'
          }
  
  lines for auto build.  We created a folder Test and under it configured Multibranch Pipeline job. Auto build is working fine till we have not configured another Multibranch Pipeline job to build from Branch B inside another Test1 folder.  Sometime the pollSCM working fine, sometime failing with below error

Please make sure you have the correct access rights and the repository exists.
  
  We are not sure what causing the issue. It will be grateful to us if you provide the solution to resolve this issue.
  
  NOTE : Jenkinsfile1 and JenkinsFile2 has same content, only difference is one is for deploy lower environment and another one is for deploy higher environment.
