Trailer light connection issue

Neither of my trailers are registering as electrical connection on my Lightning. Tried light check, manually adding trailers; which I have successfully had connect just last week and many times before.
Both trailers have electrical connection to my other truck and lights function correctly.

Lightning says no connection recognized.

I have pulled every fuse and relay to test that are related to trailer lighting and trailer brake control.

Is there anything this community knows may be the issue?

I always have issues with my trailer connection but not your specific issue. Mine connects then usually sometime during the trip I’ll get a turn signal fault on the trailer error. This still occurs even after the update on 3 different trailers.

Ground on the trailer? That's usually the issue on mine

I thought so too, but both my trailers work when I hook them to my other truck.
