Acces denied, 'mqtt-json.sh.

Hi, I'm new. I am trying to set up a mobile feed monitor using the link from the tutorial post. However, when i get to "./mqtt-json.sh, i get acces denied. I can't figure out why this is happening. I've tried to put 'sudo' in front of it, but that does not work. Can anyone help me please?

Yes, I did.

This is what i'm getting now.

 

Did you ever fix the red screens on the ADSBx setup?

 

I did not, the feed seems to work now, however.

 

"Connection refused" is a reply to a failed comunication attempt with mosquitto dispatcher.
