While I was trying my project on localhost it was working fine, using https://cors-anywhere.herokuapp.com/ since I got the CORS problem. But once I deployed the site on Netlify, it gave me the error 426 (Upgrade Required), with or without using https://cors-anywhere.herokuapp.com/. These are the messages that appear on my console:
>Failed to load resource: the server responded with a status of 426 (Upgrade Required)
>Error: Request failed with status code 426
at createError.js:16
at settle.js:17
at XMLHttpRequest.<anonymous> (xhr.js:61)
I have been searching and some people seem to have similar problem to this. I have seen solutions like having my own server to pass the requests, but I don't know how to do it and, correct me if I am wrong, wouldn't that be the same as using https://cors-anywhere.herokuapp.com/?
