xyzulu yeah it happened to me on nginx server too. I think the fix is out of reach at the moment. I think we need OLS persistent config before that bug can be fixed, that way we can configure ols to work properly with gzip or whatever setting is bugging it out.
I never experienced that issue in enterprise litespeed, but I also have gzip enabled and brotli disabled, and also the server cache disabled (I'm using page cache via plugins like WP rocket instead, for compatibility).
The "fix" for OLS at the moment is to use the LSCache plugin instead of Rocket. LSCache is better in every way anyways, and free (just a learning curve to get a perfect config).
