Ok, so, when using this URL:
https://tmi.twitch.tv/servers?channel=illusionaryone
Fine, when using some of the other endpoints:
https://tmi.twitch.tv/group/user/illusionaryone/chatters
This site can’t be reached
tmi.twitch.tv refused to connect.
ERR_CONNECTION_REFUSED
Same with the /hosts endpoint as well.
