Jenkins home page is not loading as expected after sign in

Jenkins is hosted on AKS Cluster in our setup. Jenkins UI is not opening correctly, it is giving option to sign in but after entering credentials home page is not loading correctly. Upon checking Jenkins Pod logs found below error - [Error in Pod Logs] Error deleting file /var/jenkins_home/logs/sse-events/pipeline Error deleting file /var/jenkins_home/logs/sse-events/pipeline

[Error in Health Checker Logs] Could not create logs directory: /var/jenkins_home/logs could not create listener java.nio.file.FileSystemException: /var/jenkins_home/logs/health-checker.log: Host is down

Microsoft team suggested to create another pod for Jenkins which resolved the issue. However, it again started appearing. Can someone please help what could be root the cause of this issue.
