I heard this expressions once when I was a young app developer. I was trying to integrate a piece of my code with another 3rd parties code.
I kept getting this error
Years later I ran into the guy who wrote the 3rd party software; we got talking and asked him what a YFYOYO Error was. He laughed a bit and said “it means ‘You’re Fucked, You’re On Your Own'”
So if you are working with the RSA SecurID App and you are trying to get soft tokens to work well but you keep coming up against “error communicating with server token import failed”
