Critical issue with Huawei K3765, connection lost after about 4 hours of operation

[tenthunghiem]

I have successfully configured Huawei K3765,
Documentation: https://docs.netgate.com/pfsense/en/latest/cellular/hardware.html

Everything is working properly, but every 4 hours all 3G ports of Huawei K3765 are disconnected, I have disabled the ports and restarted at Interface but nothing happens.
The only method to be able to reconnect is: Restart pfsense.
Here is my current configuration and log.

What can I do to fix the above error?

You have 5 modems? They all do this?

Do you see new USB ports detected when this happens? The modem itself could be rebooting and creating a new device.
