Cluster- EKS 1.20 Sumologic chart - 2.1.1 Fluentbit version - 1.6.10

Hi Team,

After upgrading the k8s cluster to 1.20 , fluentbit failed to start as liveness/readiness probe is failing on port 2020

Below is pod events

There is no error in logs and before the upgrade it was working fine. Please let me know in case more information is required.
