Helpful Expert Reply:
Sounds like the brake controller has lost it's connection to the trailer through the brake output circuit. Typically this issue is due to corrosion on the output circuit of the trailer connectors. Try cleaning all of the pins on your 7-way with sandpaper to see if that allows the connection to be made again.
If that does not fix the issue I attached a help article that covers brake controller troubleshooting for you to check out as well.
