For junior engineers it's really easy to fall into the trap of trying to solve everything themselves instead of asking for help when they are remote. I say this as somebody who has spent the last five years working remote team-based gigs.
Senior folks do this. All the time.

1) distance myself from the problem or 2) ask for help 3) both
Junior or not. Asking for help can be difficult
