    Hi there,
    Today i can't access to my ISPConfig panel interface. It throws the SSL ERROR: ERR_SSL_PROTOCOL_ERROR
    What are the steps to checkout if my SSL certificate it's ok?

    Thanks in advance.

    First, try to access it with "http://" and then try to access it with "https://" to see if one of them is working. It is unikely that a working ssl setup stops working out of the blue, things that I had seen more often is that the ip points to a different server or that a router catched port 8080 or that another service is listening on port 8080.
