[Redirection loop] Are incorrect Hreflang tags causing redirection loops on my website?

Situation

Brazil url of website cant be reached due to too many redirects. Indeed console shows that it is a redirect loop.

Checking the html i notice that hreflang for brazil is set to a default international url. (it should be the portuguese language version)

My question is, how is this causing the redirection loop exactly behind the scene? Whats the logic here?

Why not just redirect once to the incorrect url and be done with it? why redirect again and again when searched from brazil?

If this isnt the issue, please correct me~

Thanks guys!
