What this means:
Your device’s firewall is blocking part of the connection needed to run the TestReach app correctly. This can stop you from sharing your screen, using your camera or microphone, or staying connected during the exam.
Firewalls are security tools designed to protect your device, but they sometimes over block or restrict applications like TestReach — especially if you’re using a work or school device.
Common Problems and How to Fix Them
Problem: Windows Firewall is blocking the TestReach app
What to try:
Option A: Allow the app through the firewall
- Click the Windows Start icon, search for:
Allow an app through Windows Defender Firewall - Click the top result
- Scroll down to find TestReach (or "take a test")
- Make sure both the Private and Public boxes are ticked
- Save and restart the app
Option B: Turn off the firewall temporarily
- Open Control Panel > Windows Defender Firewall
- Click Turn Windows Defender Firewall on or off
- Select Turn off for both Private and Public networks
- Restart TestReach
Tip: You can turn the firewall back on after your exam is complete.
Problem: macOS Firewall is blocking screen recording or network access
What to try (macOS Ventura and later):
- Click the Apple icon > System Settings > Network > Firewall
- Scroll to find Firewall Options
- Click the padlock to make changes and enter your password
- Ensure TestReach is listed and allowed
- If not, add it manually from your Applications folder
- Restart the app
- macOS Monterey and earlier:
- Go to System Preferences > Security & Privacy > Firewall
- Unlock the padlock to make changes
- Click Firewall Options
- Allow TestReach or add it if missing
- Restart the app
Problem: I’m using a work or school device with restrictions
What’s going on:
Some organisations install firewalls that prevent changes to permissions or block unknown apps by default.
What to try:
- Contact your IT team and ask them to whitelist or allow TestReach
- You can share this download link: https://download.testreach.com
- Let them know firewall settings are required for screen sharing, camera, and mic access to work correctly
Tip: Restart after changes
After updating firewall settings, always restart your device and reopen the TestReach app before trying the check again.
