VisualEditor/Parsoid at closed wikis: "Error contacting the Parsoid/RESTBase server (HTTP 404)"
Hello everyone,

I'm trying to get an university internal wiki to get running with MediaWiki
1.35 (current LTS), and to move from NodeJS-based Parsoid to PHP-based
Parsoid. The wiki is private, and behind a Shibboleth-based authentication

'useSelser' => true,
'rtTestMode' => false,
'linting' => false,

$wgDefaultUserOptions['visualeditor-enable'] = 1;

// Don't allow users to disable it
$wgHiddenPrefs[] = 'visualeditor-enable';

$wgVisualEditorTabPosition = 'after';

Also note I use $wgHTTPProxy, as the server doesn't have direct access to
the internet.

Any help would be appreciated.
