ngrok doesn't lift my local django web server

Question

I have problems with negrok, it does not raise my local django web server, a few days ago everything worked correctly but a normal day, without having touched anything, it stopped working.

Run the following:

python manage.py runserver

Everything works normally and correctly.

---

Now I execute the following, in order to raise the local django server:

./ngrok http 8000

ngrok runs correctly without any problem but when accessing the ngrok link, the page is loading and everything is blank and does not work ....

This appears in ngrok:

And this appears in django:

I add the ngrok host (33822c5a.ngrok.io) in ALLOWED_HOSTS and stop giving django error, and access the ngrok link and I know that it loads again, it doesn't load the HTML, nothing, everything blank ...

Any solution? :(

Answer 1

try ALLOWED_HOSTS = ["*"] this will allow tunneling every ngrok run :)
