Restart Your Device and Router
A temporary malfunctioning of your device/TV or router may cause the Disney+ app to show the error 90 and restarting both devices will clear the issue.
Reinstall the Disney Plus App
The Disney Plus app might show the error code 90 if the installation of the Disney Plus app is corrupt. You can fix this issue by reinstalling the Disney Plus app. For illustrative purposes, we will go through the process for the Android app of Disney+.
Try a Different Network
The Disney Plus error code 90 could be the result of ISP restrictions and trying a different network may (temporarily) solve the problem. But before proceeding, check if disconnecting from a VPN (either on the device or router) solves the problem. If so, then either ISP restrictions, blockage of your device/TV’s IP by Disney, or misconfiguration of your router (discussed later in the article) is causing the issue.
Edit the Related Settings of Your Router
There are different router settings (like IPv6 or firewall on the router) that can cause the Disney Plus app to show the error code 90 and properly configuring these settings may solve the problem. But keep in mind the instructions slightly differ for some users and you may have to dig deeper to make the instructions work for you. This solution is demonstrated on Windows. If that did not work, check if a router firewall (like PFsense) is not causing the issue. Also, do not forget to check parental controls (or Circle) of the router to check if it is triggering the Disney Plus error. If the issue persists and the Disney Plus app works fine when connected directly to the Internet (without router), check if using a different router (from a family or friend) solves the issue. If so, then you may contact the ISP to acquire a different router. If the Disney Plus error persists even with a direct internet connection, then you may contact Disney+ support to remove the IP of your device from the blacklist.
