How to fix the error 'Sorry, this Adobe application is not available' on Mac OS

Are you encountering the error message "Sorry, this Adobe app is not available. To continue using this Adobe app, check your internet connection, firewall, or ad blocker settings"?
If you are, you're not alone. Many Adobe users have experienced this issue.
Having a smooth workflow is crucial when working on creative projects, and Adobe software is an indispensable tool for many designers and photographers.
However, what do you do when Adobe apps refuse to work due to internet connection problems?
In this article, we will discuss the common error message "Sorry, this Adobe app is not available. To continue using this Adobe app, check your internet connection, firewall, or ad blocker settings," and provide a step-by-step guide on how to fix it.

How to fix the "Sorry, this Adobe application is not available"

To Fix “Sorry This Adobe App Is Not Available” Error, Add Adobe Block IP Addresses List to the Hosts File and flush the DNS cache.

Step 1: Close all Adobe programs

Before you begin the troubleshooting process, make sure to close all Adobe programs.
This step is crucial to ensure that any changes made in the subsequent steps can take effect effectively.

Step 2: Open the terminal

Press Command + Spacebar to open Spotlight search, type “Terminal” and press Enter.
Terminal is a command-line interface specifically designed for Mac users. It provides a text-based environment where you can execute commands to manage various settings and configurations on your computer. 

With Terminal, you can interact with the operating system directly, perform tasks such as file manipulation, system configuration, software installation, and more, by typing in specific commands and executing them. 

It offers advanced users a powerful tool for managing and customizing their Mac system settings beyond what is possible through the graphical user interface (GUI). However, it's important to exercise caution when using Terminal, as executing incorrect commands can potentially cause unintended consequences or system errors.

Step 3: Edit The Hosts File

The Hosts file in Mac OS is a plain text file that maps hostnames to IP addresses. It is located in the /etc directory and is used to override the default DNS (Domain Name System) resolution process for specific domain names or hostnames.
The Hosts file in Mac OS works similarly to the Hosts file in other operating systems. It allows users to manually specify IP addresses associated with domain names or hostnames, effectively bypassing DNS resolution. This can be useful for blocking access to specific websites, redirecting domain names to different IP addresses, or creating custom mappings for local testing or development purposes.
To modify the Hosts file in Mac OS, administrative privileges are usually required. Users can edit the Hosts file using a text editor, such as TextEdit, and add entries in the format of "IP Address" followed by the corresponding "Domain Name" or "Hostname". Each entry should be on a separate line. Once the changes are saved, the updated mappings in the Hosts file will take effect immediately on the local Mac computer. It's important to be cautious when editing the Hosts file to avoid introducing errors or security risks to the system.

To access the Hosts file in Mac OS, open the Terminal window and type "sudo nano /etc/hosts" followed by pressing Enter.

This command will open the Hosts file, which is a plain text file used by the operating system to map hostnames to IP addresses.

You will be prompted to enter your password.

Enter your password and press Enter. Note that while typing your password, no characters will be displayed on the screen for security reasons, but your input will be registered.

Step 4: Add Adobe Block List To The Hosts File

After accessing the Hosts file, navigate to the end of the document and paste all the addresses listed in the "BLOCK ADOBE" section of this post.

In addition to those addresses, add the following addresses:

127.0.0.1 lcs-robs.adobe.io
127.0.0.1 9ngulmtgqi.adobe.io
127.0.0.1 vcorzsld2a.adobe.io
127.0.0.1 r5hacgq5w6.adobe.io

Blocking these addresses can prevent the app from checking the status of your license as they are known to trigger the error message.

To ensure compatibility with different versions, you can add the following IP addresses.

127.0.0.1 ic.adobe.io
127.0.0.1 52.6.155.20
127.0.0.1 52.10.49.85

To flush the DNS cache on macOS, follow these steps:

1. Open the Terminal application, which can be found in the Utilities folder within the Applications folder.
2. Type the following command and press Enter: "sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder".
3. You may be prompted to enter your password. Enter your password and press Enter.
4. After executing the command, the DNS cache on your Mac will be cleared, and any cached DNS data will be removed.
5. You can verify that the DNS cache has been successfully flushed by testing domain name resolution in web browsers or other network applications.

Flushing the DNS cache on macOS can be a useful troubleshooting step for resolving DNS-related issues and ensuring that your Mac is using the most up-to-date DNS information for domain name resolution.
