Unable to log in to Developer Portal – “Method Not Allowed” error

I’m trying to log in to the developer portal, but authentication fails with a “Method Not Allowed” error.
This happens every time I attempt to sign in, and I’m unable to access the dashboard or any developer tools.

**Steps to Reproduce:**

Go to the developer portal login page
Enter valid credentials
Submit the form
Error appears instead of logging in

**Expected Behavior:**
Successful login to the developer portal.

**Actual Behavior:**
A “Method Not Allowed” error is returned and login fails.

**Additional Info:**

Browser tested: chrome latest
Region: ukraine
No VPN

If you need logs, HAR files, or anything else, I can provide them.

Start by reproducing the failure from the developer portal login page in Chrome with valid credentials, following the listed steps. Check the repository's Python SDK authentication and API entry points for a connection to the portal login flow; done means the sign-in succeeds and the dashboard or developer tools are accessible.
