I tried again by creating new application on dev.twitch.tv
here I generated password https://twitchapps.com/tmi/
but again I’m getting this error
{“error”:“Unauthorized”,“status”:401,“message”:“Invalid OAuth token”}
but for validating oauth i got
{“client_id”:"…",“login”:"…",“scopes”:[“channel:moderate”,“channel_editor”,“chat:edit”,“chat:read”,“whispers:edit”,“whispers:read”],“user_id”:“605819838”,“expires_in”:0}
