I didn't get to watch this, but Spaceflight.com had this to say:
SpaceX and NASA issued a statement at 8pm UTC, confirming
ISS rendezvous on Saturday was missed. Dragon will have
other opportunities to hook up with the ISS, most likely
on Monday. However, SpaceX did confirm they were back to
two of the three thrusters, with the remaining two
expected to return to life shortly.
The root cause is still preliminary, but the initial data
points to a stuck valve that was resolved by ?jackhammering?
it open and close to free it.
Good that they got this working. Although it's a bit concerning that
one stuck valve could cause several of the four thruster pods trouble.
Of course, adding additional valves and plumbing could make this
redundant, but could introduce other possible failure modes.

"the perennial claim that hypersonic airbreathing propulsion would
magically make space launch cheaper is nonsense -- LOX is much cheaper
than advanced airbreathing engines, and so are the tanks to put it in
and the extra thrust to carry it." - Henry Spencer
