@Flydiverny I'm still facing this issue where the kes operator hangs randomly after a certain time period. I'm using the updated KES deployment(version 8.3.2) and have configured POLLER_INTERVAL_MILLISECONDS: 100000 and
WATCH_TIMEOUT: 600000. I believe this same issue was rectified previously. Is there any other parameter that we have to configure in the helm values?

Hi @Flydiverny, I am having this issue . POLLER_INTERVAL_MILLISECONDS: 30000 and WATCH_TIMEOUT: 60000 on KES version: 8.3.2. Polling fails with error ERROR, Error: connect ETIMEDOUT. Is there another way to force the watcher to restart?
