2021-03-10 02:20:03,407+0000 HealthCheckWatchdog:thread-8 WARN [c.a.t.healthcheck.concurrent.SupportHealthCheckTask] Health check Application links was unable to complete within the timeout of 20000.
And UI error:

Cause
There could be many reasons for that, depending on the health check that timed out. One of them could be busy Lucene (Indexing) operation, so the Health check thread is not able to obtain the lock within the timeout.
Workaround
Increase the Health-check timeout to 60000ms:
Add Java parameter to JVM settings (or change the parameter if it already exists in the file) - see Setting properties and options on startup for more details.
