Fix 'Check Your Internet Connection' Error Opening PDFs
Question details
The user is unable to open online government PDF files via their mobile PDF reader due to a persistent internet connection error message.

- Product
- Adobe Acrobat Reader
- Device & OS
- Samsung Note 5
- Scenario
- Attempting to open PDF files hosted on an online government website using a mobile device.
- Observed behavior
- The application displays a 'Check Your Internet Connection' error and fails to load the PDF, even though the device is connected to the internet and the app was recently reinstalled.
Ensure your mobile device is connected to a stable Wi-Fi or cellular network by verifying that standard webpages load properly in your mobile web browser.
Verify Network Stability and Update the PDF App
Ensuring a stable connection and running the latest application version can resolve most online PDF loading errors.
Connection errors are often triggered by intermittent network drops or outdated application software that fails to communicate with online servers properly.
Open your mobile web browser (such as Chrome), copy the PDF link from the government website, and paste it into the address bar to confirm the server is accessible.
If you are connected to a home Wi-Fi network, unplug your router for 30 seconds, plug it back in, and reconnect your phone to refresh your IP and DNS configuration.
Open the Google Play Store, search for Adobe Acrobat Reader, and tap 'Update' to ensure you have the latest bug fixes and network compatibility improvements.

Download the PDF Locally Before Opening
Bypassing the app's online viewer by downloading the file first can completely circumvent internet connection errors during reading.

Frequently Asked Questions
Why does my PDF app say there is no internet when my Wi-Fi is working?
The application might be experiencing DNS resolution issues, or the server hosting the PDF is temporarily rejecting the connection. Clearing the app cache or switching from Wi-Fi to mobile data can often resolve this discrepancy.
Can a router password change fix connection errors?
Changing the router Wi-Fi password itself will not fix the error. However, logging into your router's administration settings to update its firmware or change your DNS settings (such as using Google DNS at 8.8.8.8) can significantly improve connection stability for downloading files.
How do I clear the cache for my PDF reader on Android?
Go to your device's Settings, select 'Apps' or 'Application Manager', find your PDF reader app in the list, tap 'Storage', and then tap the 'Clear Cache' button to remove temporary files that might be causing glitches.
