It has to do with your squad. Disband the squad and jump on the other ship, make sure it is unsquaded and then re squad and try again. ”
I have disbanded the squad and resquadded as asked for - to no avail. I was also asked to get into another ship. There is none though. Besides, getting onto another ship on Derra IV may have a suicidal quality to it, I currently prefer not explore.

Had not tested whether I could travel before all of the above. So, I can't say for sure that the above sequence of actions has caused the release from the 'Already traveling' deadlock.
