 * Hi,
    FYI: had to disable the plugin caching option on most of the blogs I manage,
   hosted by same company, but on different instances.
 * Reason: after upgrading to 5.7, the Site Health function started showing the 
   following message
 * > There are problems with the HTTPS connection of your website Security
   >  Your
   > WordPress Address is set up to use HTTPS, but your website appears to be unavailable
   > when using an HTTPS connection. Talk to your web host about resolving this 
   > HTTPS issue for your website.
 * This problem is referenced [here](https://core.trac.wordpress.org/ticket/52783)
   for the next release.
 * More: had the problem on 3/5 blogs. Then on a 4th one when disabling the cache,
   till I deactivated the plugin
 * It’s not a bug in the plugin per se, more on WP core’s side.
    But precautionary
   principle applies for me.
 * Hope this helps.
    Sincerely DJM

   your issue, We’ll try to investigate this further and make appropriate changes
   to the core files if needed.
