same problem here

Not sure if its relevant, but I am already using litespeed cache and converter for media plugins

Hey,
I am using gutenberg, astra theme. Issue occurs also on standard theme. I found 2 issues at site health that might help find the problem (didn’t know about them before):
1.One or more recommended modules are missing – Performance

PHP modules perform most of the tasks on the server that make your site run. Any changes to these must be made by your server administrator.

The WordPress Hosting Team maintains a list of those modules, both recommended and required, in the team handbook(opens in a new tab).

• Warning?The optional module, imagick, is not installed, or has been disabled.

2. Page cache is not detected but the server response time is OK – Performance

Page cache enhances the speed and performance of your site by saving and serving static pages instead of calling for a page every time a user visits.

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, x-litespeed-cache, x-lsadc-cache, x-qc-cache.

•  Median server response time was 332 milliseconds. This is less than the recommended 600 milliseconds threshold.
•  No client caching response headers were detected.
•  A page cache plugin was not detected.
