How to fix "disallowed vary header values are present" ?

Lyre

Hello, I must say that I didn't check my dashboard often, so I only recently noticed that in the past months, my Cache Miss Rate went to a high number when it previously stayed at below 5%. I can't seem to find a way to fix it? I searched around the Forum and tried to activate the Override Cache Control Headers yesterday, I hope that does help? Or should I also deactivate my other caching plugin?

When I checked the Top Cache Miss Reason, the error shows: disallowed vary header values are present.

Does anyone with a little more knowledge have any suggestions? Cache hit rate is now pretty much 3%

Let me know if more info is needed.

Thank you in advance and sorry if I may bother you a few more times!

Lyre our cache reports are showing that the disallowed header being set on the origin server is 'Accept-Encoding,Cookie' - we can help you set up a rule in your Ezoic caching to override this and cache this content anyway on Ezoic servers, but depending on what this vary by cookie rule that's being set on the origin server is for, it could break some essential site functionality. It's worth reaching out to your host and asking what this is being used for on the origin server as a first step.

Emily I see, I will try asking my host first then. Thank you for the input. I will update on the follow up later!

Many thanks.
