[Python] Roblox API Link no longer works

I have no clue why it used to work weeks ago and now it doesn't. If anyone knows if they have like moved to another api link or whatever please kindly let me know:

https://auth.roblox.com/v1/account/pin/unlock

Ran a program using it and worked perfectly fine until those days where it gives me this error:

[ERROR] ChunkedEncodingError: ("Connection broken: InvalidChunkLength(got length b'', 0 bytes read)", InvalidChunkLength(got length b'', 0 bytes read)). Retrying in 1 seconds.
​

(the script is written to give me that error at the very end of here

def try_pin(pin, retries=3):
global tried
retry_count = 0
backoff = 1
while retry_count < retries:

r = req.post('https://auth.roblox.com/v1/account/pin/unlock', json={'pin': pin})
if 'X-CSRF-TOKEN' in r.headers:

return 'retry'
elif 'errors' in r.json():
code = r.json()['errors'][0]['code']
