502 Error after update

Hello,

We are sorry that you received an error 502: Bad Gateway after updating to the latest version of the plugin. This is a server error and server errors are usually described in more detail in the server error log. If you have access to your server error log, generate the error again, note the date and time, and immediately check your server error log for any errors during that time period. If you don’t have access to your server error log, please ask your hosting provider to look for you.

If you or your web host cannot pinpoint the cause, please provide us with a copy of the server error log for further investigation. As server logs can cover a large amount of time, please limit the error log to a few minutes before generating the error to a few minutes after the error. If the server error log does not contain any errors at the time of the issue, please enable advanced WordPress debugging with the code. Your web host can provide you with a secure path to save the error.log file.

Thanks

Can you provide steps to replicate the issue? Do you by chance experience this with Elementor? And do you have Yoast SEO 16.1 and WordPress 5.7?
