Andy Dick got a visit from cops after a guy he’s living with angrily whipped out a gun while they were live on the web.

Here’s the deal … Andy’s been staying with a YouTube personality in Las Vegas, who calls himself the Wappy Flanker, and things went awry over the weekend during their live stream. We’re told a third man went over to Wappy’s place, and an argument broke out.

That’s when Wappy pulls out a gun, and threateningly tells the visitor to beat it. In the video, you hear Andy telling his host, “Don’t shoot the gun.”

Law enforcement sources tell TMZ … police received a call from someone who was watching the live stream, and cops went to the home Saturday for a welfare check.

We’re told police spoke to Andy and the man who pulled the gun … and Andy told cops he was fine, and wanted to keep staying at the home. Officers left without citing or arresting anyone.

It appears this isn’t the first time a gun has shown up in the live stream … a day earlier, video shows the Wappy Flanker with a gun on his waistband while Andy shoos off a guy recruiting him to stream an RV trip.

The troubled comedian appears to be sleeping on a cot in the living room … and the live stream is seeking donations for Andy. 🤷🏽‍♂️
