Hi there! I see you're getting the "Error response from comms was null" message on all your Texecom Connect apps, and you can't open the apps or receive notifications. Let's get to the bottom of this together.

To start, can you tell me if this issue began recently after any changes, like firmware updates, network changes, or app updates? Also, is this affecting all devices or just specific ones?

Meanwhile, here’s a straightforward approach to try fixing this issue step-by-step:

1. Check your SmartCom or SmartCom 4G module connection:
This error often relates to communication issues between your alarm panel’s SmartCom module and the cloud. Ensure the SmartCom module powered on and properly connected to your network.

2. Restart your SmartCom module and router:
Power cycle (turn off/on) your SmartCom device and your internet router. This refreshes the connection and often resolves the null communications response.

3. Verify network and firewall settings:
Ensure that your internet connection allows the SmartCom device to communicate over required ports. Sometimes firewall or router settings block essential TCP/IP ports needed for the SmartCom communication.

4. Re-sync the Texecom Connect app with your panel:
Inside the app, try logging out and then logging back in. If prompted, re-enter the Connect Code generated by the alarm panel to re-establish communication.

5. Check for firmware and app updates:
Confirm your SmartCom and alarm panel firmware are up to date, as well as the Texecom Connect app itself. Older versions may cause communication failures.

If none of these steps work:

- There might be a problem with the SmartCom module itself or temporary cloud service disruptions.
- Double-check if you can access your account via the Texecom web portal.
- As a next step, you might want to get in touch with Professional Installer Technical Support at [email protected] or call +44 (0) 1706 212524 (weekday 8:00–18:00) for further diagnostics.

If you'd like, I can guide you through these steps in more detail—just let me know! Are you able to access your SmartCom hardware currently?
