An error occurred while connecting to REST API

@rstrah This information is very valuable. Now we can make sure it’s a server problem that is blocking connections. Contact the administrator of your server and ask why connections are blocked.

Your request is performed using the https protocol, this protocol and port are not blocked by the server.
The screenshot you provided shows a 504 Gateway Time-out server error – it occurs when Nginx cannot receive a response from any service (for example, PHP-FPM) for a long time.
If you need to increase the timeouts for executing scripts, please indicate to what value you need to raise the time limit.

@rstrah Try to increase this value, e.g. twice.

Hello.

Increased script execution time and server response timeout.
Please check if the plugin works.

I noticed this plugin starts converting photos from the beginning (2013 year), is it possible to somehow launch it from today to the beginning of the site?

@rstrah It is not possible. When converting again, only images that have not been converted before are converted.

@mateuszgbiorczyk What about the error that appears?Any ideas on how to fix this?

@rstrah There is nothing else you can do. It’s just that your server has limited performance and this error can occur from time to time. If you run the conversion again, the previously converted images will not be converted again.

Therefore, when an error occurs, start converting until you can convert everything. I understand you have a huge amount of images, but there’s nothing else I can do. These are the limitations of your server.

now this error occurs immediately, but there is one nuance, while I was converting with a checkbox (convert everything again) everything works (4.5 hours, then an error), as soon as I stopped putting this checkbox even 1 photo does not want to be converted

@rstrah Please download this plugin version:

What exactly shows up just below the “An error occurred while connecting to REST API” error? On the plugin settings page – not in Dev Tools.

I noticed a very strange coincidence, the cycle of your program reaches the same file all the time and after the crash, I ran tests and deleted a couple of webp files from the very beginning, it converted them again and crashed in the same place where it always was, it seems to me due to the fact that there is a long enumeration of all the photos and a 504 error occurs (or an array overflow)
