Cannot Push for some reason

hello, i’m trying to use github to push the code, however when it ask me to login, no matter if i try to connect with a token or by connecting through browser, i get an unexplained error while sending the request, after that it ask me my username and passsword but even if i put them in, it tells me that using username and password has been deprecated, and still negate me access
so i have no idea how to resolve this issue, what can i do? attached a link to the error message
