Description

I'd like to request a feature where it retry to download video when WinError 10060 occured. My internet is not that good and I'm getting this at random occasion. Of course, when I re-invoke the same command it tries to resume where I left off, but again because my internet is not very good, it happends again at random occasion. It's somewhat annoying because when I start invoking the command, I just left the command running in background and doing anything else for few minutes and got disappointment when it actually fails to download because WinError 10060. It would probably a good idea to retry few times and if error keeps occuring, then give up.

Please do not tell me to fix my internet. This is somewhat the decent internet I can get in my area and I have no idea if my ISP is able to fix this.

I attached traceback it occured. I don't know if it's relevant for feature request but I'll put it anyway.

For any work on this you must provide reproducible environment.

I'm having the same problem.

Solution should be a simple 1 line of code:

if WinError 10060 then retry
