It sounds like the rain is causing a short somewhere and that is causing the error and the brakes to stop functioning.

Make sure that the splices from the magnets to the wiring from the connector are water tight. You can use heat shrink tubing such as # DW05745-10 and even liquid electrical tape, # SWC50122.

When inspecting the trailer wiring, look for any exposed copper strands or pinched wires and fix as needed.

The trailer side and vehicle side connectors could be getting water in them. It would be difficult to keep water out. When everything is dry, use some dielectric grease, # 11755, between the electrical connections to keep out moisture.
