We are unable to activate [product name]. Either your computer is offline or the clock on your computer is set incorrectly, causing a connection error. An Internet connection is required. If you see a test successful message (see screenshots below), you have access to the activation servers. Still have problems? Operating system hosts files map host names to IP addresses. Open the hosts file with a text editor such as Notepad. To find the hosts file, open Finder and then choose Go > Go to Folder. If you are unable to locate the file, it means that the hosts file is hidden. If your computer is behind an authorization proxy server, disable it. Locate the GlobalSign Root CA certificate. I'm trying download the adobe apps, and this message pops up...'Unable to reach adobe servers, check firewall and time zone settings' pops up on the Creative Cloud brower. I've turned off Firewall and my Timezone settings is correct. And I've looked online and I couldn't find any solutions!I can't uninstall the app to reset it as it says 'Can't uninstall as you currently have apps that need the Creative Cloud' which I understand as I do have Adobe XD installed. So was wondering if anyone has actually solved this??I need to know asap as I'm doing a job for an agency, and theres not much Adobe support help lines.Also I see some people on this forum, linking people to 'Direct Download of apps pages'.. Have you installed and run any "cleaning", "optimizing", "speed-up", anti-virus or VPN apps on your Mac? Give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; • Verifies your startup disk and attempts to repair directory issues, if needed• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)• Prevents Startup Items and Login Items from opening automatically• Disables user-installed fonts • Deletes font caches, kernel cache, and other system cache filesNOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. I keep getting the error "Unable to reach Adobe servers". I have tried uninstalling and reinstalling the Creative Cloud App as described in various community post. Still the problem persists.The second Creative Cloud loses connection all Adobe Apps close. This is unacceptable. I am a working professional and need the software to be functioning. I have been using Creative Clouds for years with no problems on the exact same network, with same ISP etc.This problem suddenly started. So this is NOT a network or connection issue. This is an Adobe issue. Firewall is disabled and Creative Clouds and Apps works just fine on other PCs and Macs on the same network/internet connection.Creative Cloud is installed on a month old PC running latest all updated version of Windows 11. The computer runs subscriptions from Autodesk, Chaos Group and others without any problems whatsoever. If you have a Creative Suite 5.5 subscription serial number, you can no longer activate the software on a new computer. Creative Suite 5.5 subscriptions are no longer supported, and new activations for this subscription type are not available. If you already have Creative Suite 5.5 installed on your current device, this change doesn't affect you. The error message indicates that you may have network connectivity or stability issues. The operating system hosts files that map host names to IP addresses. An incorrectly configured hosts file can affect your computer's ability to connect to Adobe's activation servers. Check for updates for your operating system and install the updates. Some operating system updates may restrict outgoing Internet connectivity for security reasons. Create a new administrator account and try installing or updating the app. Use the Adobe Creative Cloud Cleaner tool to remove Adobe-related files from your device and perform a clean installation of your Creative Cloud desktop app. First things first. I used to have a Win 10 home edition where I use Adobe PS and Lightroom with the creative cloud app. OK, I got in touch with Adobe support, I had a remote session with one of their guys, he tried everything: firewall, user settings, windows defender, reinstalling adobe creative cloud, we spent around 45 minutes in that session. change to a new admin user profile. So, I thought to upgrade to Win 10 pro. I already read every helppage regarding this issue on the adobe site, and they claimed it is a Windows issue. This question was migrated from the Microsoft Support Community. I have had this exact same issue since (roughly) June. I migrated my system between old and new PCs last weekend using laplink. Tried setting up an extra user with full admin rights but still get the same error code. Tried cleaning CC off and doing a fresh install to no avail. No avail. The same. Every-absolutely-thing else is working with the internet connection, except the marvelous creative cloud app. Same issue. I tried just now disabling every option in the windows defender and tested it.
Common causes and quick checks
- Time and date settings - ensure the system clock matches the correct time and timezone, as activation can fail when clock skew occurs.
- Internet connection and proxies - verify network access, disable problematic proxies, and confirm firewall rules allow Creative Cloud traffic.
- Hosts file configuration - an incorrectly configured hosts file can block Adobe activation servers; review and restore if needed.
- Administrative rights - run the installer or Creative Cloud Cleaner Tool with an administrator account.
- System updates - install pending OS updates, since some updates affect network connectivity.
- Security software - temporarily disable or adjust antivirus/endpoint protection that might block Adobe services.
Step-by-step troubleshooting flow
- Check time, date, and timezone settings; correct any discrepancies and test activation again.
- Test direct access to Adobe activation servers; disable proxies and ensure the firewall allows Creative Cloud traffic.
- Inspect the hosts file for incorrect mappings to Adobe servers; edit if necessary using a text editor with administrator rights.
- Disable or adjust VPNs and security software temporarily, then attempt activation.
- Boot into Safe Mode on Mac or Windows and test, then reboot normally and test again.
- Run the Adobe Creative Cloud Cleaner tool to remove Adobe traces, then perform a clean reinstallation of the Creative Cloud desktop app.
- If possible, create a new administrator account and try installing or updating the app from that profile.
- Verify OS updates are installed; some updates may restrict outbound connectivity for security reasons.
Notes on specific scenarios mentioned in user reports
Some users report that even with the firewall disabled, Creative Cloud apps may still lose connection on certain machines or networks. In these cases, comparing the affected system with a functioning one on the same network can help identify machine-specific configurations. If an older Creative Suite 5.5 subscription is referenced, note that new activations for that subscription type are no longer available, though existing installations may persist on some devices.
Additional actions that often help
- Create a new administrator account and attempt installation or updates from that account.
- Use the Adobe Creative Cloud Cleaner tool to perform a thorough cleanup before reinstalling the desktop app.
- Ensure that wireless peripherals (for example, keyboards) are properly powered, as certain hardware issues can affect boot and setup processes.
Potential outcomes and what they indicate
- Successful test message indicates access to activation servers and may simply require a reattempt with corrected settings.
- Persistent inability to reach servers, despite normal network access, often points to host file issues, proxy/firewall blocks, or a need for a clean reinstall.
- If issues persist across multiple devices on the same network, the problem may involve the router or ISP-level blocks; consider testing on a different network.
