Some True Detective fans who went online to watch the season finale were likely disappointed.

Enough people logged on to HBO Go to watch the season ender that the streaming service crashed, according to its Twitter account.

"Due to overwhelmingly popular demand for ‪#TrueDetective, we've been made aware of an issue affecting some users. Please try again soon," read a tweet sent out Sunday night.

Some viewers who logged on to the service -- you have to be an HBO subscriber to access it -- saw a "fatal error" message indicating that the service wouldn't load. It's unclear how many users were affected.

The anthology crime drama series wrapped its first, eight-episode season Sunday night. Newly minted Oscar winner Matthew McConaughey and Woody Harrelson star as two homicide detectives tracking a serial killer.

The show has proven a hit with viewers and critics. The inaugural telecast drew 2.3 million viewers, giving HBO its biggest premiere since Boardwalk Empire (4.8 million) in 2010.

McConaughey has said that he won't be back for a second season should HBO renew the series.

McConaughey said "We won't be back for season two. Season one was finite. Eight episodes, that's the [end of conversation]." During an interview at the 86th Academy Awards backstage.

McConaughey then discussed the difference between working on "True Detective" and the film that won him his Best Actor Oscar for his role in "Dallas Buyers Club":

"True Detective was basically like a six‑month film. It was one director, eight episodes, 450 pages, basically a 450‑page script. Six months shooting on film. Very considerate. Much more considerate than Dallas Buyers Club. We shot that with one camera, no lights and a tiny crew in 25 days. I was going for the quality and the experience. I don't know what this means, I don't know what the result will be. What can I get an experience out of, Matthew? That's the question I was asking myself."
