The Docking Autopilot has a glitch that let him lock up right before the final push from time to time. Switching it off and directly on again normaly solves that and will dock immediately. https://forum.kerbalspaceprogram.com/topic/154834-112x-anatid-robotics-mumech-mechjeb-autopilot-2143-4th-march-2023/page/168/#comment-4247646

Rightclick on the MechJeb Tab and you can drag it around.

The problem is that it only happens sometimes. Most of the time it is working fine and sometimes it simpy stops right before docking. I was docking and undocking several times on diferent dockingports to provoke this behavior For me it looks like the autopilot is locking up before the last push.

For me switching the Docking Autopilot off and on again solved the problem every time, I have seen this behavior in every version of MechJeb so far. It happens sometimes, i can't force it to happen. Here is a Savefile, the ship is the "Docking Trainer S" , Only Mech Jeb and Modulemanager in this install. Hope this helps.

In order to get MechJeb work that way you need Module Manager too

MechJeb2: 2.12.0.0 is for KSP 1.11, at the moment only the Dev Realeases suport KSP 1.12 To enable the Dev versions you have to add the Repository in Ckan under -> Settings ->Ckan Settings -> Repositorys for Metadata ->New.

If you use the Mk2 Clamp-O-Tron, it is broken. It has it's controlpoint facing in the wrong direction, The bug is confirmed, so all we can do is to wait for the next patch.

I used it to fly from Kerbin to Duna. Tested again, and it is working again. Is your install of KSP a clean one?

As far as i can see Module Manager and MechJeb 2 DEV RELEASE 1082 seems to be working fine with KSP 1.12. The warning at the start that MechJeb is made for an older version of KSP, can be ignored.

Just tested with MechJeb 2 - DEV RELEASE 2.10.0.0-1008 , no problems. Edit: Second test with a more Modded install, MechJeb 2 - DEV RELEASE 2.10.0.0-1008, again no problems. Btw. do you have a pilot in your ship? If not, do you have a radioconnection to Kerbin?

Looks like the problem was on my KSP install. Kerbal Engineer Redux (the only mod installed besides Mechjeb and Module Manager of course ) was causing the problems with Mechjeb somehow. After deinstallation of Kerbal Engineer Mechjeb was working fine. I have reinstalled Kerbal Engineer after that and again everything was working fine ( both versions of Mechjeb, normal and latest Dev version tested ) So you can stop chasing ghosts now. And thanks for this great mod, without it KSP would not be the same!
