Checking the error logs would be the best thing to do if you’re not seeing the intended result.

tail -20 /var/log/nginx/error.log

That’ll at least detail what errors are resulting. From there, we can see if there’s anything that’ll help us to identify an issue.

@jtittle

The truth, I do not have the level to interpret this output of the command tail, but you manage to know what is happening? . I keep investigating for myself, but I’m still in a mystery

Also check the access.log and as I explain before I can enter all the other urls, but “libros” that if I can do it in my development environment, in production I can not access

First of all I am very grateful of you, since you help me. And that has a lot of value.

This turned out to be my friend, I hope it throws some data that can serve

@maxgonpe

Nothing seems to really look out of ordinary to me, so the issue, based on what I’m seeing, would be somewhere in the production environment.

There’s something, somewhere, that differs between your development and productions servers. It’s, unfortunately, not something that you’ll find within NGINX because all NGINX is really doing is taking the request and proxying it over to your app.

What I’d recommend doing is retracing your steps and make sure that everything you setup for the development server is identical to what you’re running for production. When it comes to detailed setups and configurations, it’s easy to miss a step here or there and ultimately, that can lead to an application not working as expected or completely failing.

@jtittle

Hmmm, well.

I am intrigued that I do not have any separate development and production configurations, since what I run with python3 manage.py runserver 0.0.0.0.8000 and it works, I assume that when I exit the development environment and run the nginx start, it should work same. That is why I am worried about this, since it is taking away time and I can not get out of the trap.

In case of any idea in specific, please let me know and anyway, thank you very much for your inconvenience and for everything that always helps me.

thanks take care

@maxgonpe

What does your server block for NGINX look like?

@jtittle

Sorry that I did not answer you last night, but here in the end of South America it was late and I had to go to sleep. Today I greet you with a few “good morning” and I send you this one to strike down here; However, tell me if you can see any obvious flaws or suddenly recommend that I re-do the site completely again, but I’d like you to find out what it might be, because otherwise, it’s going to be a factor of uncertainty regarding python and django .

I will be waiting for your answer to see what to do, if you insist on discovering the fault or on the contrary redo everything again, although I prefer the first option.
