Connection refused - fingerprint

[ahof1704]

Hi!

Thank you for the useful tutorial. It was very good.

I am facing an issue:
Error: SSL error 40
HTTP GET failed with code -1

I already have my token created, but I am not sure about the SLACK_SSL_FINGERPRINT... how can I check if the one you guys have in your code is still valid?

Thanks!
Antonio.
