First thing to check is for corrosion on the trailer wiring connectors on the running light circuit. Nearly everytime a single circuit stops working on trailer wiring it's due to corrosion in the connectors preventing the connection being made. Sometimes it can be a bent or damaged pin too.
I attached a help article on trailer wiring for you to check out as well.
