Invalid Response

[burnt-melon]

Hello,
I am currently trying to open the webpage that's hosting my flask script but whenever I try opening the link google (and every other browser) just said

"This site cant provide a secure connection,
127.0.0.1 sent an invalid response.
ERR_SSL_PROTOCOL_ERROR"
and whenever I look back at my terminal it says

"
127.0.0.1 - - [25/Jan/2021 15:59:16] code 400, message Bad request version
"

and a bunch of UTF-8 encoded things which im not gonna show since it may be confidential (And it also has unknown characters so I cant decode).
I am sure that talisman is causing this because when I remove the Talisman(app) it works perfectly fine but when I do add it, the same error occurs until I remove it and restart my laptop.
My script:
`
from flask import Flask

from flask import render_template

from flask_talisman import Talisman

app = Flask(name)

Talisman(app)

@app.route('/')

def index():
return render_template("index.html")

if name == "main":
app.run(debug=True)

`

Having the same issue. Did you manage to find a solution?

My guess is you have a localhost server you try to access over https://, but that would fail (unless you configure SSL for your localhost server). You could try to explicitly ask your browser to access the localhost server on http:// and set the force_https=False argument in Talisman while developing on localhost.

Note also that it looks like this project have been forked and is more actively maintained over there (#78).

Thanks alot Anders, placing force_https=False did work. Cheers!
