LSCache caching functions on this page are currently unavailable!

#1
hello my WordPress website display: LSCache caching functions on this page are currently unavailable!
this website uses OpenLiteSpeed as a reverse proxy the backend is an Apache server when I install the LiteSpeed Cache for WordPress it displays " WARNING
LSCache caching functions on this page are currently unavailable! To use the caching functions you must have a LiteSpeed web server or be using QUIC.cloud CDN. "
I have checked the FAQ page but have not been able to get an answer.

My other WordPress website also uses OpenLiteSpeed as a reverse proxy, and an Apache server as the backend but it runs well. I have checked the two websites and servers Same environment, and the same Settings.

I don't know what's wrong. Can someone give me a little help?
thank you very much!
