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 (implemented with https://mediawiki.org/wiki/Extension:PluggableAuth and https://www.mediawiki.org/wiki/Extension:Shibboleth_Authentication). However, I can't get past "Error contacting the Parsoid/RESTBase server (HTTP 404)" error. My current VE-related config: wfLoadExtension( 'Parsoid', '/mnt/wiki/data/code/vendor/wikimedia/parsoid/extension.json' ); wfLoadExtension( 'VisualEditor' ); $wgVisualEditorParsoidAutoConfig = false; $wgParsoidSettings = [ 'useSelser' => true, 'rtTestMode' => false, 'linting' => false, ]; $wgVirtualRestConfig['modules']['parsoid'] = []; $wgVirtualRestConfig['modules']['parsoid']['forwardCookies'] = true; // Enable by default for everybody $wgDefaultUserOptions['visualeditor-enable'] = 1; // Don't allow users to disable it $wgHiddenPrefs[] = 'visualeditor-enable'; $wgVisualEditorTabPosition = 'after'; I tried to allow read/write access for the server's public and loopback IP, but that didn't unbreak visualeditor. I also skip Shibboleth configuration if the request comes from the server itself. The wiki is hosted as HTTPS-only, I'm not sure whether that causes any issues. Also note I use $wgHTTPProxy, as the server doesn't have direct access to the internet. Any help would be appreciated. Thanks, Martin Urbanec
