but in chromium with same tor's proxy (socks5) it success login and show post
maybe i need use some data from chromium like cookies or useragent?
ps: http-proxy create from socks5 by privoxy

Try to use all headers which the browser adds. Not only cookie and user-agent.

In particular sec-fetch-*, sec-ch-ua-*, upgrade-insecure-requests headers.

socks5

You need to specify that in the proxy URL:
--proxy socks5h://127.0.0.1:8118

maybe i need use some data from chromium like cookies or useragent?

You can export and use your browser cookies with gallery-dl:
https://github.com/mikf/gallery-dl#cookies

sec-fetch-, sec-ch-ua-

Those are HTTP/2, which is not used in gallery-dl.
Logging in works with just the default headers.

[AlttiRi]

Those are HTTP/2

Not only, they are send to any https page independently is it http/1.1, or h2. ("Protocol" can be checked in DevTools, you need to enable the column by RMB in Network log table header)

(and localhost)

I've had the same problem: gallery-dl could log-in but the API returned a 400 Bad Request for every link. I had to login via browser and provide my birthdate that Instagram requires for personalization now. It works again now. Use a throwaway account, provide false information.
