Hello, 

We have an intermittent issue with Jenkins being stuck while waiting for github to acknowledge notification or github comment from Jenkins.

When it appears we can also see some jnlp timeouts and Jenkins is not able to launch jobs anymore. 

We have to restart Jenkins to solve the issue. 

Context : 

Jenkins is running on EKS (K8S 1.21) 

Jenkins version : 2.332.1 lts

Jenkins plugins related to Github : 

• GitHub APIVersion1.301-378.v9807bd746da5
• GitHub Branch SourceVersion1583.v18d333ef7379
• Github Custom Notification Context SCM BehaviourVersion1.1
• GitHub Pipeline for Blue OceanVersion1.25.3
• GitHub pluginVersion1.34.3
• Pipeline: GitHubVersion2.8-138.d766e30bb08b
