I deployed a vercel app and connected it to an api

let me explain it first this api and vercel app already works on an existing server like backoffice.xxx.com as the vercel app and api.xxx.com as the api

im trying it on the new server and new vercel account

testbackoffice.xxx.com
testapi.xxx.com

but it wont get through the login screen . it stucks. as i said before all the files and configs was existing ones and i am almost sure about i changed everything correctly . So what should i do


when i do curl
