Can`t connect to server
First time using Linode so this is probably me doing something wrong during the instalation. From my putty:

Can anyone explain to me what I am doing wrong? I have uploaded the flask app and it runs without problems locally. I have installed the NGINX and all the python scripts. I have configured flask using json and installed unicorn but I have done something wrong. I do not know why or how to start debugging.

I'm not sure if you already saw this, but we have another post on our site about what sounds like the same issue that you may want to check out.
The suggestion there is that something is bringing gunicorn back up, and you need to find that and stop it in order to kill all the processes.
This StackOverflow forum explaining options for killing processes may also help.
Someone more familiar with these applications may be able to provide a more complete answer, but I hope something in those resources gets you moving in the right direction.
Thanks for the answer. I actually got the solution from one of the guys on the Linode team. The premade app kept restarting the gunicorn3 that I killed so once that was handled everything went smooth. But thanks for the reply!
