Since upgrading to the 2.16.xx series we have constant problems, and yes 2.16.02 is the latest version running.
Sometimes there is a crash report generated and sometimes the server process is still running but connections are not accepted so it looks like the website is down.
When the server is restarted everything runs fine (latest ACME certificate is Sep.28,2021) but 3 or 4 days later the server once again either crashes or just stops taking connections.
If you are running on Window, you might be facing the same problems as I am.
You can try to disable http2 support
* Open the console
* Click on the Server Configuration icon
* Click on the Parameters icon
* Press Edit next to "Advanced Parameters"
* Press Edit next to "HTTP/2 Parameters"
* Check Disabled
* Press OK
* Press OK
* Press OK
* Press Restart
The issue is being worked on.
