Some combinations appear in real text but do not mean what learners often assume.

Using about as the main complement

Undaunted is normally followed by by when referring to obstacles.

Using in instead of by for obstacles

Use by for the thing that does not discourage someone.

Confusing time expressions with complements

After can describe timing, but it does not replace by for obstacles.
