The 25-year-old arrived from Paderborn in January 2018, but he has failed to impress enough to remain at the club.
He scored five goals in 43 appearances and will now start the next chapter in his career.
He had been looking to leave after falling down the pecking order this term.
Srbeny's move was confirmed on the official Norwich City website.
The club's statement read: "All at Norwich City would like thank Dennis for his contributions and wish him well in his future career."
