Should I throw away my bisque?

I bought 2 lbs of pre-cooked and frozen, defrosted crawfish, which I then reboiled with carrots, celery, onion, garlic, brandy, etc. to make bisque.

It’s been simmering for about 30 minutes and it doesn’t smell “good,” by which I mean I’m not thinking “mmm I can’t wait to eat this.” It has an earthy, vaguely ammonia-like smell to it.

Should I throw it all away? Is this normal?
