How to fix connection errors

To resolve issues related to connectivity, work out the solutions one by one and pick the next solution if required.

Solution 1: Test your connection to Adobe activation servers.

To determine if you have access to the Adobe activation servers, click this link.



Still have problems? Go to the next step.


If you see a test successful message (see screenshots below), you have access to the activation servers. Try activating or starting your software.



Creative Cloud and CS6: Test successful



CS5 and CS5.5: Test successful

Note:

You may get an "Access Denied" message when you click the CS5/CS5.5 link. This is still a confirmation that you can access the activation servers. Try activating or starting your software. If you need help with your activation code, see Redemption code help.

Still have problems? Proceed to "Reset your hosts file."

Solution 2: Reset your hosts file.

Operating system hosts files map host names to IP addresses. An incorrectly configured hosts file can affect your computer's ability to connect to Adobe's activation servers.

Note:

Creative Cloud users: Resetting the hosts file can also resolve errors such as "The Creative Cloud applications are available in trial mode" or "Trial expiration."

Extract the downloaded file, and then run the Limited Access Repair tool in Admin mode.

• Windows: Right-click the tool and choose Run as Administrator.
• macOS: Double-click the tool and enter the admin credentials to continue.

Reset the hosts file manually

If the issue is not fixed even after you run the Limited Access Repair tool, reset the hosts file manually:

To reset the hosts file on Windows, do the following:

Navigate toC:\WINDOWS\System32\drivers\etc.

Open thehosts file with a text editor such as Notepad.

Check for any Adobe-related entries in thehosts file.



If there are no Adobe-related entries in thehosts file, no further troubleshooting is required.

However, if there are Adobe-related entries in thehosts file, proceed to the next step.

If there are Adobe-related entries in thehosts file, move the file to the desktop, for example by dragging.

Delete the Adobe-related entries from thehosts file.

Make sure that you do not delete any other entries.

Save thehosts file that you edited in the previous step.

The updatedhosts file should not have any Adobe-related entries.

Move the file from desktop to the original location:

C:\WINDOWS\System32\drivers\etc

When moving the file, select the Replace option.

To reset thehosts file on macOS, do the following:

To find thehosts file, open Finder and then chooseGo > Go to Folder. In the box, type the following location and then pressReturn:

/private/etc/hosts



If you are unable to locate the file, it means that thehosts file is hidden. Type the following command in terminal to unhide the file, and then repeat Step 1.

chflags nohidden /etc/hosts

Open thehosts file using a text editor such as Text Edit.

Check for any Adobe-related entries in thehosts file.



If there are no Adobe-related entries in thehosts file, no further troubleshooting is required.

The updateshosts file should not have any Adobe-related entries.

Solution 3: Make sure that you can access secure sites.

Adobe's activation servers are on secure (HTTPS) sites, so your computer must be able to access these types of sites.

Follow these steps to make sure that you can access secure sites:

Start an Internet browser, such as Firefox or Internet Explorer.

Typehttps://www.adobe.com in the address bar, and then pressEnter.

Can't access secure sites?

Make sure that your computer's clock shows the correct time and is set to the correct time zone.

If your computer is behind an authorization proxy server, disable it. For instructions, consult your network administrator or your proxy server documentation.

If your computer is behind a firewall, make sure that the firewall is not blocking the activation server through ports 80 and 443.

For instructions on allowing access to the activation server, consult your network administrator or your home network's firewall documentation.

Note:

If your firewall requires an executable, specify PDApp.exe, located here:

• Windows: Program Files\Common Files\Adobe\OOBE\PDApp\core
  
• macOS: Applications > Utilities > Adobe Application Manager > core > PDApp

Solution 4: Check the GlobalSign Root CA certificate.

The Adobe sign-in (Creative Cloud) and activation (Creative Suite) processes require the GlobalSign Root CA certificate.

Follow these steps to make sure that the GlobalSign Root CA certificate is installed and enabled.

Click Start and typecertmgr.msc.

Navigate toCurrent User >Trusted Root Certificate Authorities > Certificates.

Right-clickGlobalSign Root CA and selectProperties.
