Unable to detect the presence of page cache

magic

Hi there,
I have OLS server with Lite Speed cache installed. From time to time i am getting this error (as in the picture attached). Then after a while it's gone and all way around.

This has happened to me several times, even when I was using cPanel + LiteSpeed Web Server with caching plugins active. Usually, WordPress can't detect the cache because of missing HTTP headers or issues with internal loopback requests. In most cases, the cache is working fine — it's just that WordPress's site health check is a bit sensitive.
