I wanted to contribute a fix for it, and was trying to find in the source code where this is defined but I couldn't find it.
But after looking at https://docs.readthedocs.io/en/stable/user-defined-redirects.html, seems like the redirects are defined somewhere else outside the source code. (It starts with Log into your readthedocs.org account.)

In that case, this might not be a good first issue for someone to look at, as it is listed in https://github.com/psf/requests/contribute

@nateprewitt do you by chance have access to the project on read the docs? If so could you share access to my user? (same username: ewdurbin)

@ewdurbin, I don’t have access to any of the doc infrastructure actually. We’d need @kennethreitz to get us added.

@nateprewitt do you have a RTD username I can add to the project?

It should be the same nateprewitt. Thanks!

Hi @ewdurbin , @nateprewitt

Thanks for responding. If I understand correctly, the RTD username will help solve this issue as it will grant access to readthedocs?

Hi @deveshks, apologies for the back and forth. Yes, I think we're getting RTD setup so we have proper access and then can hopefully address the underlying issue.
