Error messages can't reach Server Mac

Question

Hello everyone, I hope you can help me. I have installed Creative Cloud and Acrobat Pro on my iMac and on my MacBook Pro. When I start it, I get the following error messages, see attachment. I hope you can understand it, unfortunately it is in German.

I have checked everything, the router the firewall everything, there is nothing that should block this. I have even tested other networks.

Basically everything works, it's just the messages on startup. Does anyone have a tip for me as to what the problem is?

Hello Hagen!

I hope you are doing well, and thanks for reaching out and sharing all the information.

Try the suggestions from the following articles and let us know how it goes: https://adobe.ly/4cOFqN8. How to fix network connectivity issues when downloading Adobe apps

How to resolve connection errors with Creative Suite applications

For Acrobat, please ensure you have the latest version of Acrobat installed on the machine: 25.001.20458. Planned update, Apr 15, 2025. Check for any pending updates from the Menu > help > check for updates, install the updates, restart the app and the machine, and check. For more information, see this: https://adobe.ly/4cOFrAG.

What's the current version of Mac installed? Are you getting the error message with Acrobat as well? Sign out and sign back in from Acrobat and the Creative Cloud Desktop app installed, then sign back in again, and see if you still get the error message.

Disable Firewall / Antivirus Temporarily: Even if the settings look okay, try temporarily disabling your firewall or antivirus to rule out interference (especially from apps like Little Snitch or third-party antivirus). Then launch Acrobat and see if it connects.

Allow Adobe through the Mac Firewall: Go to System Settings > Network > Firewall. Click Options (or "Configure"). Make sure Creative Cloud, Acrobat, and Adobe Desktop Service are listed and allowed. If they are not present, add them manually. See this article to allow the network endpoints: https://adobe.ly/42Ig1jE

Clear Adobe Credentials from the Keychain. Corrupted credentials sometimes cause sync issues. Open Keychain Access. Search for anything containing Adobe. Delete all entries related to Adobe. Then, relaunch Creative Cloud and sign in again.

If the issue persists with Acrobat, please use the Acrobat Cleaner tool to remove the installed app, restart the machine, ensure all the updates related to the operating system are installed, and install Acrobat.

Let us know how it goes.

Thanks,

Anand Sri.
