Hi! I will try my best to help you. I have also faced similar problems learning. Have you configured the permissions on the steemconnect website correctly? What url are you using to login to steemconnect? Check if it has the comment authority on the scope "scope=vote,comment"
I think it is a scope issue, you can read more about scope at:
https://github.com/steemscript/steemconnect/wiki/OAuth-2
Thank you for your attention
I'm using scope=login,vote,comment
and
I have posting authorize
I did try again before this comment ( even I used manualy this link https://app.steemconnect.com/authorize/@qbdp before runing )
but I still get error
error_description:
"Broadcaster account doesn't have permission to broadcast for @qbdp"
I'll read again (and again) your links, thank you so much.
