List of steps to reproduce (step by step, including full links if applicable):
- Create a plain vanilla MediaWiki site with HTTPS
- In LocalSettings.php, set $wgServer using a protocol-relative URL, such as $wgServer = '//mywiki.com';
- Confirm that the wiki can edit and save pages.
- Install VisualEditor and load it in LocalSettings.php like so: wfLoadExtensions(array('VisualEditor'));
- Click "Edit" to edit a page with VisualEditor. This should work fine.
- Type some text on the page you are editing. This should work fine
- Attempt to save the edited page. The save fails with the error: Error contacting the Parsoid/RESTBase server (HTTP 415)
- Now, in LocalSettings.php, set $wgServer to use an explicit https URL, such as $wgServer = 'https://mywiki.com';
- Edit and save a page using VisualEditor. It should work fine.
What happens?:
When $wgServer is protocol-relative, a dialog appears, Error contacting the Parsoid/RESTBase server (HTTP 415)
What should have happened instead?:
VisualEditor should save pages correctly.
Note: The problem does not occur on an HTTP (non-secure) site. VisualEditor saves pages correctly if $wgServer is protocol-relative.
Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc.:
MediaWiki 1.37.1
VisualEditor 0.1.2
See ticket T268277 for early attempts to debug this problem. It was originally misidentified as a $wgGroupPermissions issue.

Here is my complete LocalSettings.php, sanitized:
