Welcome MizzardHp!

If you have used Snap Endpoints, then the entities should be mathematically connected.
You can check this when you create a Polyline from existing elements.
Select both entities and then activate the Polyline tool. When the result is one continuous entity, their endpoints matched.

You can probably use the plugin List entities too. Select both entities, then activate the Plugin and hit ENTER. In the entity list you should see endpoints of both entities to compare them.

Or, just for testing, connect the other ends with a line too and try to apply a hatch to this closed area. If the hatch is ok, the entities are connected. Otherwise the Hatch tool prints the gap coordinates and length in the command history box.

This might be just an inaccuracy from the underlying drawing library. See my post https://forum.librecad.org/Bug-with-Line-and-Circle-Intersection-mismatch-on-snap-Intersection-tp5717031p5717032.html

If there is indeed a gap between the entities, you can connect them with trimming.
In this case it might be a matter of drawing order. This always depends on the given constraints and entity types. I often draw a circle instead of curves, then divide it on intersections and delete the unwanted part.
