Getting 500 Internal Service Error and Curl Error 60

[deep-daya]

At first I got a cURL error 60: SSL certificate problem when the code tries to get the login form. So I changed the GuzzleHttp Client with 'verify' => false.

That seemed to fix the error. But now I keep getting a 500 Internal Service Error when I try to get the auth tokens

Can you help me figure out why this is the case?
