 * Hello: 
   When connecting Amazon S3 or Cloudflare R2, I get a 500 error on the 
   route:
 * /wp-json/wpmcs/v1/verifyCredentials
 * What could be causing this?
    Thank you very much for your time.

 * Hi [@javierarcheni](https://wordpress.org/support/users/javierarcheni/)
 * Sorry for the inconveniences caused.
 * It seems to be compatibility issue.
 * Can you please enable the wp_debug. And try again the configuration. If again
   error happened please share the debug log from the log file.
 * It seems to be a critical issue. So log will be written in the log file. Please
   share the log to identify the issue.
 * Thanks

 * Hi Rahul:
   Thank you for your quick response. I’ve enabled the wp_debug but no
   error in the debug_log. Apparently all connections to routes /wp-json/wpmcs/v1/*
   return error 500. Perhaps some files are missing in the plugin??I’ve checked 
   in another site and same error.
 * Appreciate your help.

 * Hi [@javierarcheni](https://wordpress.org/support/users/javierarcheni/) ,
 * We have tried live plugin in our review servers, as well as the [https://playground.wordpress.net/](https://playground.wordpress.net/).
 * We couldn’t reproduce the issue.
 * So, we need an exact error that caused the issue. Only wp_debug is the option.
   Enable wp_debug, wp_debug_log and wp_debug_display and check for more detailed
   error tracing.
 * If still there is an issue, you can share a temporary credentials with admin 
   access of your staging site to our mail. We will check from our end.
 * Thanks

 * Hi again [@rahu1](https://wordpress.org/support/users/rahu1/)
 * Unfortunately no errors are displayed. I created an admin account to your info@
   Fill free to access. It’s a staging site, so you can tinker whatever you want.
 * Thanks again.

 * Hi [@javierarcheni](https://wordpress.org/support/users/javierarcheni/)
 * Unfotunately we didn’t receive any email from you. Can you send a manual email
   instead of password reset automation mail. Staging server may have mail sending
   issues
 * Thanks
