Hello. thanks for the replies :-) Now, one year later, i tried to get working my Perl Script. ( Chatserver ) I have installed it on localhost and i created a certificate with mkcert. Now, everytime, i want to login into my page i get an error in the browser:

Secure Connection Failed

An error occurred during a connection to 127.0.0.1:22222. SSL_ERROR_RX
+_UNEXPECTED_RECORD_TYPE
[download]

In my console i got this error:
