I'm running version 2020.09.20 and the same exact thing happens for me for these browser-playable videos:

https://www.dailymotion.com/video/xklb33
https://www.dailymotion.com/video/xklcyv
https://www.dailymotion.com/video/xklgty
https://www.dailymotion.com/video/xklgur

(But most videos from that very channel downloaded fine!)

I can repro the issue with the links above on 2020.11.21.1. First analysis shows that videos play fine in browser, but let's look at them in detail.

https://www.dailymotion.com/video/x7u7219 autoplays in 720p quality, but not when you switch to 1080p quality:

Sorry! An unexpected error has occured.

So the error is on the side of dailymotion for this video.

To fix it, download in 720p. First check the format names using -F, then download the best available one with --format:

What youtube-dl could do is to switch to another format when one is unavailable. So this looks like a duplicate of #3721.

Interestingly, dailymotion seems to offer each format several times, using separate mirrors I assume.

So for some videos (e.g., x5luang), you may find that http-720-1 is not available, but http-720-0 is. (This must be the case when the browser plays 720p.)

For other videos (e.g., x5m3g74), you may find that the 404 error appears mid-video, which may again be solved by choosing a different format for the same resolution. My guess is that you can even resume downloads started at one mirror with the data from a second mirror (if bitrate etc. is the same), but do verify that.

I can confirm exactly what bersbersbers said—I can download the videos now!
Two of them downloaded stochastically (xklgty and xklcyv) but the other
three never succeeded, despite several hundred (automated) attempts, but
using the --format selector for a 480 instead of any of the four 720's,
they downloaded immediately :)
Perhaps the reproducibility problem is that DailyMotion uses geoip on the
client's IP address and makes some formats completely unavailable by
cutting off all mirrors for it. But that wouldn't explain why it's
stochastic. Perhaps it's based on ping instead?
