talisman | Straightforward fuzzy matching , information | Natural Language Processing library

I have been running flask-talisman on my development server and everything checks out fine. Yet, with the same code and requirements installed on my dedicated server for production (Almalinux), just adding Talisman(app) after app = Flask(__name__) results in the webpage not loading with a redirection to https://localhost:8000. The error message that I precisely get on my browser after typing in the domain is:

This site can't be reached - localhost refused to connect

I am running Nginx 1.14.1 with gunicorn 20.1.0 and supervisor. The server is connected to the internet and without using Talisman it has run smoothly so far.

List of things that I tried without any effect

• temporarily stopped firewall
• restarted nginx
• both tried to access the website through its domain and IP address - the redirection to localhost:8000 remains
• tried to run the app on other ports, e.g. 8000 for testing
• stripped down the code to a mere mini tutorial that runs well on my development server but not on my production server. So I figured it can't be the app itself.
• checked error logs and there is literally nothing, not in the nginx error log or python app error log. Access log shows nothing usual, the same as if everything checks out.
• searched the Internet and found nothing that would point in the right direction and explain the failed redirect to localhost:8000

Here is a stripped down tutorial code that should run but doesn't run on my server:

CSP implementation: Flask-Talisman
The attribute that needs to be set: content_security_policy_report_uri

There does not seem to be a lot of information out there on how to capture this report
I can't find anything specific in the Flask-Talisman documentation

As Flask-Talisman only sets headers, including the report-uri, I imagine this is outside the scope of the extension anyway

All resources I've found have roughly the same function:

The only really detailed explanation I've found for this route is below (it is not related to Flask-Talisman however)

I did a Talisman setup for my project repository and now I am unable to commit changes to a branch. It aborts with the following error. Please help!

I haven't found this answer anywhere, and have been on the lookout for a few months, so my apologies if I'm overlooking something that should be obvious. Self-taught and came upon a rather vexing gap in my knowledge here.

In an rather complex yarn of connected pieces, I have two globally-scoped (basically static) variables and an array of character types outside of the main onclick function, as such:

I'm trying to configure OAuth authentication with GitHub apis, on Superset 1.0.1. Following the docs, I added the following lines in superset_config.py

I am using the Flask-Mail library for my Flask application to send a default welcome email to the user when they sign up to be added to the newsletter. After debugging the library I found that it can only handle one connection at a time to send a message and will then automatically close the connection. If the backend sends an email to another user while a connection is still open then it throws this exception: raise SMTPServerDisconnected("Connection unexpectedly closed: " smtplib.SMTPServerDisconnected: Connection unexpectedly closed: [WinError 10054] An existing connection was forcibly closed by the remote host. I want to be able to queue the mail Mail library to send a new message to another recipient after the connection has closed but currently it keeps throwing the error I mentioned above when I attempt to queue the function to send a message.
