Lines will not connect after array

I have designed a single tile which I tried to expand to a 2X2 format. I did so by using the array. Next step is to connect the inner lines since I want to offset them. I’m not able to connect the inner lines; Even after removing the doubles. i’ve got 2 questions 1) is there a way to connect the lines? 2) if not possible, is there another fast way of drawing. In the end the format has to be 3X7 and I’ve to create 17 similar formats, therefore I’m looking for a fast way of drawing. Thanks for helping me out. I included the file and marker the lines I want to connect red (just for understanding where my problem is)

lines not connecting.lbrn2 (22.1 KB)

I didn’t quite understand what is wanted. However, analyzing the file, there are small deviations that may be influencing it.

I don’t know the reason, but at all line intersections there is a deviation and also open lines.

Conditions I know for joining lines:

Once the conditions are met, select the lines you want to join and, using the “Edit” menu, select “Auto-Join” or directly use the shortcut Alt-J after selecting the lines.

To emphasize @Kuth’s first point: only two lines may join at a node. This means you can’t have a four-way (or three-way) intersection as you show.

The doc about open vs. closed shapes may be helpful:
