- I cannot connect my wallet to the site

When I navigate to https://cryptocodeschool.in/auth, I cannot connect my wallet to the site, preventing me from doing anything like claiming a crypto bot

- [ ] **To Reproduce**
Steps to reproduce the behavior:

1. Go to https://cryptocodeschool.in/auth
2. Click on `Connect Wallet`
4. See error in console

- [ ] **Expected behavior**
It should have opened my Temple wallet to authenticate my account

Start by reproducing the failure at https://cryptocodeschool.in/auth in Windows 10 and Chrome, then inspect the Connect Wallet request and its CORS preflight in the browser console and network panel. Done means clicking Connect Wallet opens Temple and authenticates successfully without the reported XMLHttpRequest or missing Access-Control-Allow-Origin error.
