Site Health Status, server response time is still slow

Hello,

Browser Cache, Set cache control header, Set entity tag (ETag) are enabled and I stil get the next error:

“Page cache is detected by looking for an active page cache plugin as well as making three requests to the homepage and looking for one or more of the following HTTP client caching response headers:cache-control, expires, age, last-modified, etag, x-cache-enabled, x-cache-disabled, x-srcache-store-status, x-srcache-fetch-status.”

How to fix this?

Thanks.
