Parse the received URL string with urllib.parse.urlparse() to extract the hostname and port number (instead of splitting the URL to extract the hostname and port). parse_remote() previously split the host string with ":" to get the host and port number, but splitting may result in a list of 3 strings (e.g., 'ws://192.168.4.1:8266' would become ['ws', '//192.168.4.1', '8266']. The code would crash because of the double forward slashes at the beginning of the host string.
