Flask uWSGI and Nginx : systemctl status myproject : FAILED

First of all, I am already running a similar Python flask web server on the machine.

I am following this tutorial in order to host a web server with Python Flask.
And in the 5th step (No problem so far), when i test with :

systemctl status myproject

I get

serveurB.service - uWSGI instance to serve serveurB
 Loaded: loaded (/etc/systemd/system/serveurB.service; enabled; vendor preset: enabled)
 Active: failed (Result: exit-code) since Mon 2021-06-28 14:25:45 UTC; 1min 53s ago

Jun 28 14:25:45 ecocathlon systemd[1]: serveurB.service: Failed with result 'exit-code'.

In which

myproject = serveurB
myprojectenv = serveurB (yes same name, i misstyped that one but i don't think it is the issue)
user = sydney

All my previous steps and files seem correct.

Thanks in advance,
Sydney R.

    They key line in the error message is this one:

    Jun 28 14:25:45 ecocathlon uwsgi[7992]: bind(): Permission denied [core/socket.c line 230]

    bind is the method that will "bind" your socket to a port for listening and you are receiving a "Permission denied" error. That means you are using a low number port (< 1024) and are not root.

    I would recommend changing the port to something higher than 1024 since running an app as root can be dangerous. There are other solutions as well but they are out of scope for this answer.

    You have to be careful about the naming when setting up your project on digital ocean. The best way to make sure you not getting any naming error just make the project name consistent from the project and when setting up your server as well. For this I would suggest that you double check your nguni service file and see if you actually referenced your uWSGI project.
