Actually, I think maybe it's caused by the parameter I give behind 'gvsearch' is too large that there are not enough search results on Youtube. But I think if this is the problem, it's better to tell the user about how many search results they can get, not just reporting errors.

Thank you for your response!

[CatWang]

@yan12125 I tried another time, it seem that if I use 300 instead of 500, at first, it goes well. But if I start it another time, it will report the seem error about service unavailable.

[CatWang]

@yan12125 If I use just gvsearch with no parameters, the problem still exists. So may be the problem is not related to the parameter.

[yan12125]

@CatWang Could you paste the output of this command?

Thanks. The last try seems good.

I tried another time, it seem that if I use 300 instead of 500, at first, it goes well. But if I start it another time, it will report the seem error about service unavailable.

If I use just gvsearch with no parameters, the problem still exists. So may be the problem is not related to the parameter.

From those descriptions seems your connection is not so stable. By your name I guess you're live in China? AFAIK Chinese government blocks connections to Google services with GFW. Maybe you're another victim?

[CatWang]

Hahahahah, yup, I'm Chinese. But I ran this program in Hong Kong, so there would be no problem connecting to Google and Youtube. Anyway, I have already wrote another program and downloaded videos I wanted to do research. Thank you for your patient answers! @yan12125

[yan12125]

OK. If you don't need youtube-dl anymore, feel free to close this issue.

[Diyaa-Alk]

I have had the same exact problem (error 503):
it says (https can't contact with server)
and all I did is run the same command again and it worked for me on windows 10 64 bit

[Diyaa-Alk]

so if you get this error again, just rerun the same command and it will work.
