MediaWiki - VisualEditor Extension: (curl error: 28) Timeout was reached

Question

I am getting the following error displayed while trying to edit a page with the aid of Visual Editor (It did not work previously yet):

Error loading data from server: apierror-visualeditor-docserver-http-error: (curl error: 28) Timeout was reached. Would you like to retry?

I think the above is a port issue as port 8142 cannot be accessed for some weird reason as I executed the command:

curl -L http://40.68.204.191:8142

and received the following response:

curl: (7) Failed to connect to 40.68.204.191 port 8142: Connection timed out

I have installed the VisualEditor extension by doing the following:

1. Download VisualEditor from the ExtensionDistributor page. After getting the code, I saved it into the /opt/bitnami/apps/mediawiki/htdocs/extensions/VisualEditor directory of my wiki.

   I have installed version 1.32 (latest stable MediaWiki)

2. I have installed Parsoid by following the installation instructions which can be found here: https://www.mediawiki.org/wiki/Parsoid/Setup

3. I have added the following code into my LocalSettings.php file:

   wfLoadExtension( 'VisualEditor' );
   

   and 

   ##### VisualEditor Config #####
   
   // Enable by default for everybody
   
   $wgDefaultUserOptions['visualeditor-enable'] = 1;
   
   // Optional: Set VisualEditor as the default for anonymous users
   
   // otherwise they will have to switch to VE
   
   $wgDefaultUserOptions['visualeditor-editor'] = "visualeditor";
   
   // Don't allow users to disable it
   
   $wgHiddenPrefs[] = 'visualeditor-enable';
   
   // OPTIONAL: Enable VisualEditor's experimental code features
   
   #$wgDefaultUserOptions['visualeditor-enable-experimental'] = 1;
   
   $wgVirtualRestConfig['modules']['parsoid'] = array(
   
       // URL to the Parsoid instance
   
       // Use port 8142 if you use the Debian package
   
       'url' => 'http://40.68.204.191:8142',
   
       // Parsoid "domain", see below (optional)
   
       'domain' => '40.68.204.191',
   
       // Parsoid "prefix", see below (optional)
   
       'prefix' => '40.68.204.191'
   
   );
   

4. I have changed the 2 lines of code within the config.yaml file (used for Parsoid configuration) which can be found within the "/etc/mediawiki/parsoid" folder on my virtual machine:

   # Configure Parsoid to point to your MediaWiki instances.
   
           mwApis:
   
           - # This is the only required parameter,
   
             # the URL of you MediaWiki API endpoint.
   
            
   
             #  uri: 'http://localhost/api.php'
   
             uri: 'http://40.68.204.191/w/api.php'
   
             # before >>  uri: 'http://localhost/w/api.php'
   
             # The "domain" is used for communication with Visual Editor
   
             # and RESTBase.  It defaults to the hostname portion of
   
             # the `uri` property below, but you can manually set it
   
             # to an arbitrary string.
   
            
   
             # domain: 'localhost'  # optional
   
             domain: '40.68.204.191'  # optional
   
             # before >> domain: 'localhost'  # optional
   

5. I have also added SELINUX=permissive at the end of the semanage.conf file within the /etc/selinux folder.

I have followed the following instructions to install Parsoid and VisualEditor:

https://www.mediawiki.org/wiki/Parsoid/Setup

https://www.mediawiki.org/wiki/Extension:VisualEditor

VisualEditor and Parsoid are new extensions which I have installed on our MediaWiki.

Answer 1

Your node should be at version 6 or newer to run Parsoid 0.9.0, to check this run:

node -v

If its not at least version 6 try updating node, you should be able to do so with the following:

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

Try changing the address in Config.yaml and LocalSettings.php to localhost

And if you get a HTTP:401 follow the instructions here
