Hostagent Logs Shows "Cert Update Thread Is Waiting With Timeout of 24 Hours"
Problem
Node doesn't converge to the Platform9 Management Plane. Hostagent logs show entries like below every 24 hours. However, nodes remain in a disconnected state on the PMK GUI.

Cause
- The issue happens due to the node clock is not in sync.
$ timedatectl Local time: Wed 2023-06-07 10:02:28 UTC Universal time: Wed 2023-06-07 10:02:28 UTC RTC time: Wed 2023-06-07 09:59:17 Time zone: UTC (UTC, +0000) NTP enabled: yesNTP synchronized: no RTC in local TZ: no DST active: n/aResolution
- Sync the node clock using timedatectl and hwclock command followed by pf9-hostagent service restart.
$ sudo hwclock --hctosys- Verify if clock is synced.
$ timedatectl Local time: Wed 2023-06-07 10:28:46 UTC Universal time: Wed 2023-06-07 10:28:46 UTC RTC time: Wed 2023-06-07 10:28:46 Time zone: UTC (UTC, +0000) NTP enabled: yesNTP synchronized: no RTC in local TZ: no DST active: n/a- Restart the pf9-hostagent service.
$ sudo systemctl restart pf9-hostagent- Verify if the service is running and the node started converging to the management plane. GUI should show the node as connected.
