Problem 1: (resolved - Thanks @Ranjith Thangaraju)
I tried to access this website via postman, but I can't do this because I got an error: https://i.sstatic.net/Dmfj8.png
Then when I try to access it on chrome - there's no restriction at all - I can access it: https://finance.vietstock.vn/
Why is this happening and how to resolve it?
Problem 2:
When I access this page [https://finance.vietstock.vn/CEO/phan-tich-ky-thuat.htm], there is one of the APIs that I've tried to call from the postman but I couldn't, could you please point me a solution for this?
