Silicon Valley

HBO | 10:00 pm

Richard (Thomas Middleditch) finds himself caught up in a web of lies as the hit sitcom wraps its fourth season with "Server Error." Meanwhile, Jared (Zach Woods) lays out his personal exit strategy and Jack (Stephen Tobolowsky) takes a big gamble. Elsewhere, Gavin (Matt Ross) plans a comeback. HBO has ordered a fifth season, but T.J. Miller, who plays Erlich, will not be returning.
