- Product
- Adobe Software
- Device & OS
- not provided
- Scenario
- Attempting to route a PDF form for digital signatures using a desktop PDF application.
- Observed behavior
- A 'No Internet Connection' error dialog appears and blocks the process, despite the user having an active internet connection.
Verify that your internet connection is active by opening a secure website in your browser. Additionally, confirm which specific digital signature service you are trying to use within your PDF software, as some require background services that might be temporarily down.
Re-authenticate and Verify Firewall Settings
Refreshing your login session and ensuring your PDF application is not being blocked by system security tools is the most effective way to restore connection to the signature servers.
Network connection errors in PDF software often stem from expired login tokens or overzealous firewall rules blocking the application from reaching the signature server.
Open your PDF desktop application, navigate to your profile or account menu in the top right corner, and select 'Sign Out'.
Restart the application entirely, click on the profile icon again, and sign back in using your credentials to generate a fresh authentication token.
Open your computer's firewall or antivirus settings, navigate to the 'Allowed Apps' or 'Exceptions' list, and ensure your PDF application has permission to access both private and public networks.
If you are on a corporate network, check your system's proxy settings to ensure the signature service domains are not being blocked or routed incorrectly.
Send via the Web Service Interface
If the desktop application continues to fail, you can bypass local software blocks by uploading and sending your PDF directly through your provider's web portal.

Frequently Asked Questions
Why does my PDF app say 'No Internet Connection' when my Wi-Fi is working?
This false error typically occurs because the specific application is blocked by a firewall, proxy settings are misconfigured on a corporate network, or the software's secure login token has expired and cannot communicate with the cloud server.
Does reinstalling the PDF software fix the connection error?
Sometimes. However, signing out and back in or whitelisting the application in your firewall usually resolves the issue much faster than a full reinstallation.
Can I sign a PDF offline without an internet connection?
Yes. You can apply a self-signed digital signature or standard e-signature to a document locally on your computer without internet access. An internet connection is only required if you are using a cloud service to route the document to external signers.
