Currently, when I try to share a website on Facebook, The images set in the OGP tags are not being displayed.

In the OGP settings, the image is set as follows

We have confirmed that there is no particular problem with the description of the settings.

When we checked the above URL with the share debugger, we confirmed that "418" is displayed in the response code field. However, regarding the "418" here, the community site etc. to investigate the cause, but could not find any specific action to be taken, I am not sure what kind of action is needed.

I would appreciate it if you could answer the following questions.
