Learn how to fix internet connection issues such as no connectivity, limited connection, or unable to access network drives during the download or installation process for Adobe apps.
If you experience connectivity issues while downloading or installing Adobe apps, such as no internet connection, limited access, or inability to access network drives, follow these solutions in the given order:
You aren't connected to the internet
You need an active internet connection to download and update apps.
Once connected, select Retry in the error dialog box to install the app again.
Your internet connection is unstable
If you're connected via Wi-Fi, try a wired connection. If you're connected via a wired connection, try using a different cable.
Software firewall has restricted access to your computer
Software firewalls can restrict internet access and cause download errors (commonly error 205).
- If prompted, allow the Creative Cloud desktop app to access the Internet.
- If not prompted, temporarily disable software firewalls to check if they're blocking access. For help, refer to your firewall software documentation.
Your antivirus software is blocking the download
If the issue persists after checking your software firewall, temporarily disable the antivirus software. Check your antivirus documentation for information on temporarily disabling your antivirus.
Hardware firewall or proxy server is causing installation issues
Many organizations use hardware firewalls and proxy servers to block software from accessing external servers. This typically applies to all computers within a corporate network, but most home networks don't use hardware firewalls or proxy technology.
Contact your IT department for firewall or proxy information.
Configure your browser with the provided proxy or firewall settings.
Configure your corporate firewall to allow access to these servers:
- ccmdl.adobe.com:80
- swupmf.adobe.com:80
- swupdl.adobe.com:80
Install your app again.
Hidden proxy settings are causing connectivity issues
In some instances, network connectivity issues may arise due to hidden proxy settings on Windows machines. To resolve this issue, verify whether any hidden proxies are configured on your machine and then reset the proxy settings.
Note
To restore normal functionality and reset detected proxy settings, ensure you have administrator access.
In the Windows search bar, type Command Prompt.
Right-click Command Prompt and select Run as administrator.
In the Command Prompt window, type netsh winhttp show proxy and press Enter.
If the details of hidden proxies display in the Command Prompt window, type netsh winhttp reset proxy and press Enter to reset proxy settings.
Restart your device.
Install your app again.
Hosts file is incorrectly configured
If you're still experiencing issues, your hosts file may be incorrectly configured. The operating system uses hosts files to map host names to IP addresses. An incorrectly configured hosts file can affect your computer's ability to connect to Adobe's activation servers. Learn how to reset hosts file.
