pam auto miner will not dock space engineers

Hi, I hope there is someone still reading this help forum.
I will tell you my problem: I have a mining company fully configured to use PAM, everything works correctly except for two things:

1st When the mining company fills its load it has the PAM configured to return home, it does so and here comes the first problem, when it gets in front of the connector it does not connect, it does not even get close enough for the connectors to be magnetized, either because it is a cube away from the connector or to the sides.
2nd The second problem has to do with the first, when it does not dock automatically, I manually dock the ship to the connector, when the ship is empty of load PAM does not disconnect the connector to continue with the work, but it does get into a state to continue with the work and you look at the thrusters trying to advance.

I am very confused, I have been hours and hours with the problem and I have done everything and I cannot get it to dock.

Note: The connector that it connects to is on the stern of the ship, and is labeled [PAM].
I have used this script for years and it has always worked well, although I had not touched the game for 3 years I have returned and what a disappointment that this script does not work well. :_____(
