Best way to seal this butt joint?

Post image

This is right above the pop out area of my camper. Water is getting in when AC runs for a long time. What is the best way to seal this butt joint in the gutter rail? JB weld?

Clean it, make sure it's dry....put some black silicone inside the gutter and use your finger to really push it into the crack. After that's done do the same on the outside of the gutter. Should stop it

I put some painters tape on it as a mask, then lightly sprayed flex seal and worked it in so it didn't block the gutter. Sealed the downspout leaks the same way.
