Troubleshooting 'unhealthy' docker container

A previously stable container recently started reporting as 'unhealthy' during startup.  The internal docker log does not report any errors and I'm able to access the containers active URL as expected. Version hasn't changed recently from what I can tell.

Calling a docker inspect command I get the following output (truncated to show health status):

What's the best way to troubleshoot given that the container appears to be running without issue?
