View should show related articles from shared reference field - relation from a relation
In order to fetch resources under specific Megazine, you need to have the Magazine ID on your contextual filter instead of the Article ID. Here is my suggestion:

Play with your URL pattern to add the magazine ID to it (You can do this using Pathauto and Token Module). Once you install those two modules define a URL Pattern for your articles (/[node: field_related_magazines:entity]/[node:title])  

Now you each article page will have a URL with Magazine ID to it so, you can change your contextual filter to get Magazin ID from the URL using "Raw Value From URL". This will give you the result you are looking for.
