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,” can be a frustrating experience. This issue is not uncommon among Adobe users.

Adobe software is a crucial asset for many professionals in the creative field, including designers and photographers. An uninterrupted workflow is vital for productivity and efficiency. However, connectivity issues can disrupt this workflow, causing Adobe apps to become unresponsive.

This article provides a comprehensive guide to address this prevalent issue. It delves into the specifics of 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.” The guide offers a systematic approach to resolving this issue, ensuring that your Adobe apps run smoothly and your creative process remains undisturbed.

Step 1: Terminate Adobe Applications

Ensure all Adobe applications are closed before initiating the fix. This is a crucial step to guarantee the effectiveness of the subsequent steps.

Step 2: Launch Terminal

Use Command + Spacebar to activate Spotlight search, input “Terminal,” and press Enter. Terminal is a command-line interface for Mac users that facilitates the execution of commands to manage computer settings.

Step 3: Modify The Hosts File

In the Terminal window, input “sudo nano /etc/hosts” and press Enter. This command opens the hosts file, a plain text file that your computer’s operating system uses to map hostnames to IP addresses. You will be prompted to input your password. Although no characters will appear on the screen as you type, your input will be recorded.

Step 4: Append Adobe Block List To The Hosts File

After opening the hosts file, navigate to the bottom of the document and paste all the addresses listed in the “BLOCK ADOBE” section of this post. Add the following addresses, which are known to trigger the error message:

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 verifying the status of your license. If the error persists, consider adding more addresses to the list.

Step 5: Save and Exit The Hosts File

After adding the addresses, press Control + X to exit the file. When prompted to save the changes, press Y, and then hit Enter. You will then return to the Terminal’s main screen.

Step 6: Purge The DNS Cache

In the Terminal, input the following command to flush your computer’s DNS cache, ensuring the changes made to the hosts file take effect:

sudo killall -HUP mDNSResponder && sudo dscacheutil -flushcache

Step 7: Reboot Adobe App

With the necessary changes made to your computer’s settings, you can now restart your Adobe app. The “Sorry This Adobe App Is Not Available” error message should no longer appear, and the app should function properly.

Additional Tips For Resolving “Sorry This Adobe App Is Not Available” Error

If the hosts file method proves ineffective, consider the following steps to resolve the “Sorry This Adobe App Is Not Available” error:

• Verify Your Internet Connection: A stable and reliable internet connection is essential. Poor internet connectivity can lead to connection issues with Adobe’s servers, resulting in authentication problems.
• Review Your Firewall Settings: Ensure your firewall settings are not obstructing Adobe’s servers. If your firewall is blocking the servers, you may need to add exceptions to permit Adobe’s servers to connect.
