Troubleshooting Terminal Connection Issues with Momence POS
The following suggestions cover the most common issues that may prevent your Terminal from connecting when launching the Momence POS:
Ensure Network and DNS Settings Are Correct
Make sure your device is connected to the same Wi-Fi network as the card reader.
Set your device’s DNS to 8.8.8.8 as the only DNS server (use 8.8.4.4 only if a secondary is required).
If you’ve just changed your DNS settings, clear your browser’s cache and cookies, then quit and restart the browser.
Here’s how to change DNS on macOS:
How to Clear Cache on Google Chrome:
Open Chrome.
Click the three-dot menu in the top-right corner.
Go to Settings > Privacy and security > Clear browsing data.
Select All time for the time range.
Check Cookies and other site data and Cached images and files.
Click Clear data.
Quit and reopen the browser.
Wi-Fi Frequency
Your router and computer should both be on a 2.4 GHz network.
How to Check Your Wi-Fi Band:
On a Mac:
Hold Option/Alt and click the Wi-Fi icon in the top menu bar.
Check the channel information for “2.4 GHz” or “5 GHz.”
On Windows:
Connect to your Wi-Fi network.
Open the network panel from the taskbar.
Click “Properties” for the connected network.
Scroll to “Properties” and check “Network Band.”
Using Wi-Fi Boosters?
If you're using a booster, make sure its frequency matches the router’s. If they differ, the Stripe POS device may not work properly.
Allow List Requirements
Stripe Terminal requires that both the POS application and the card reader can access certain domain names. These must be allow listed on your network.
You can also restrict your router to specific devices by adding their MAC addresses to the Access Control list. This can usually be found by logging into your router (e.g., Xfinity) and checking the Security or Network settings.
