Description of your issue, suggested solution and other information

This report is a copy of #20275. That report was closed with the label "duplicate" without actually linking any other report. Also, it seems like it was closed with the justification that a different format has to be selected, but then of course youtube-dl should automatically select that other format. I asked for the report to be reopened, but that didn't happen and I got no response. I also can't comment there anymore or reopen the issue myself, so I create this issue instead.

Only this video fails. Confirmed in a browser that the URL that youtube-dl generates (https://r3---sn-4g5e6nsr.googlevideo.com/videoplayback?key=yt6&source=youtube&pl=26&mime=video%2Fmp4&keepalive=yes&aitags=133%2C134%2C135%2C136%2C137%2C160%2C242%2C243%2C244%2C247%2C248%2C278&lmt=1412909645873222&expire=1552055838&clen=227971046&initcwndbps=333750&mn=sn-4g5e6nsr%2Csn-4g5ednee&c=WEB&ipbits=0&mm=31%2C29&gir=yes&mv=m&dur=533.766&mt=1552034157&id=o-ALoRWzTtSaNT8y9Clz8cq9uR5LrD4SRXAM8jWHAAYCcO&ip=80.187.102.81&requiressl=yes&fvip=3&signature=6EABE2E390003D3E3F1318D0E3CE2E3BB6B8A9E2.7BA8FB9F41519CE07E499534CA547E53AEDBB0A9&itag=137&ei=vimCXOZzyqDWAtrnh7AF&sparams=aitags%2Cclen%2Cdur%2Cei%2Cgir%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Ckeepalive%2Clmt%2Cmime%2Cmm%2Cmn%2Cms%2Cmv%2Cpl%2Crequiressl%2Csource%2Cexpire&ms=au%2Crdu&ratebypass=yes) does indeed give a 503 error.
