If anyone faces this problem when using wordpress + health check plugin + openlitespeed:
curL error 28: Operation timed out after X milisseconds
could not confirm that the wp_version_check() filter is available
I found a simple and rapid solution, it seems that openlitespeed has some incompatibilities with .htaccess so you have to manually set to “Yes” in Server Configuration 》General 》 Rewrite Control 》 Auto Load from .htaccess
