Narrative:

During cruise the ap failed and was unable to be reset inflight so the rest of the flight was hand flown. During the approach we encountered wake turbulence from a C-17 and executed a go around. ATC assigned runway heading to 4000 and reaching 3500 feet we received a traffic alert and an RA which we complied with. We were then vectored back for another approach without incident.
