Domain tests 200.png not responding as expected

[izmeez]

This may only occur on some platforms.

When creating or editing a domain, even when the domain is working, the following error is displayed:

https://example.com/modules/domain/tests/200.png is not responding as expected and may not be configured correctly at the server level. Server code 0 was returned. 

Furthermore, the checkbox option Ignore server response warning is not preserved when checked and saved with the error continuing to be displayed while the module appears to continue to work.

I am still seeing this message. Is any one else seeing it?

@izmeez I can't reproduce the first part. I made sure all warnings and errors set to display and log. I edited an existing domain and created a new domain.

Also, I looked but couldn't find checkbox "Ignore server response warning" - where is it?

Go to domain list at /admin/structure/domain and click to edit a domain. Then at the bottom of the form you will see Ignore server response warning. Even with it left unchecked everything appears to work fine, just the notice is displayed.

This is what my edit screen looks like:

Looking at the code, this only appears if there is an error with the domain_check_response():

  // If the server did not respond properly, do not allow this record to be set
  // as the default domain.
  if ($error) {
    $form['is_default']['#description'] .= '<br />' . t('<strong>This domain did not respond correctly. It cannot be set as your primary domain unless you select <em>Ignore server response warning</em></strong>.');
    $form['ignore'] = [
      '#type' => 'checkbox',
      '#title' => t('Ignore server response warning'),
      '#default_value' => 0,
    ];
  }

@yorkshire-pudding That's interesting, because it does appear at the bottom as the very last option.

So, this must be environment specific.
