Visual Editors fail on new mediawiki installs (on Synology NAS)

Sorry, don’t know how to upload images. I had a screen capture of that error and that led me to Parsoid. The error is:

Error contacting the Parsoid/RESTBase server: (curl error: 7) Couldn’t connect to the server

I did look at the MediaWiki page on Extension:VisualEditor and that and the error led me to Parsoid. But maybe that is wrong. Here is from that page ( ):

The VisualEditor extension allows for editing pages as rich content. There is also a project of the same name aiming to create a reliable rich-text editor for the Web and for MediaWiki.

Before MediaWiki 1.35, the VisualEditor extension relied on a separate Parsoid parser service that needed to be installed and enabled in order to edit pages with it; this is now bundled with MediaWiki core.

When I say “built” the image, I am just downloading the official MariaDB and MediaWiki docker image on my NAS, then running through the steps to setup the database via the docker container install/configuration on my NAS and then doing the same for the MediaWiki container while also connecting the MariaDB database to it.

I got the Official MediaWiki image from here (can’t put more link as a new user …) on hub dot docker dot com) and used that as the basis for my Synology NAS docker configuration including ports and file/folders.
Got the Official MariaDB docker image from here too.

Clicking on “edit” just opens an HTML text area without any visual editor…
I click on “Edit” and get the error message above. A bar moves across the top and then the error pops up.

Have you installed mediawiki on your desktop to see if it works?
No, I suppose I can try that too.
