I've been struggling with that issue for a week now. Everything was fine until I added 3 TGIDs to my Fav list and uploaded to the scanner. All of sudden, "
Nothing to Scan".I checked the profile and made sure ALL
Service Types were selected. Still nothing. At some point during multiple attempts to load a working profile I checked the
Service Types list and found that NONE were checked and I could not select them manually. WTF? In desperation I created a new profile and built a new Fav list and uploaded it. Eureka! It worked. Later I made a change to the list and uploaded it and was back to the same
Nothing to Scan problem. This time I uninstalled Sentinel and reinstalled it. Bingo, worked again. Dunno what's going on but right now it works and I'm afraid to make a change.
