I modified your code app.py code to the below, along with your current hello.html and login1.html this is working fine.

from flask import Flask
from flask import request
from flask import render_template, redirect, url_for, request
APP = Flask(__name__)
@APP.route('/')
def login1():
      return render_template('login1.html')
@APP.route('/login', methods=['GET', 'POST'])
def login():
    error=None
    if request.method == 'POST':
        if request.form['username'] != 'admin' or request.form['password'] != 'admin':
            error = 'Invalid Credentials. Please try again.'
            return redirect(url_for('login1'))
        else:
           return render_template('hello.html', error=error)

if __name__ == '__main__':
      APP.debug=True
      APP.run()

Try this.

First change the line in app.py

@APP.route('/?', methods=['GET', 'POST'])

to

@APP.route('/login', methods=['GET', 'POST'])

And then in login1.html, change these lines to corresponding lines.

<form action="/login" method="post">

<input type="text" placeholder="Username" required="" id="username" name="username" />

<input type="password" placeholder="Password" required="" id="password" name="password" />

Update

    <form action="/login" method="post">
        <h1>Login Form</h1>
        <div>
            <input type="text" placeholder="Username" required="" id="username" name="username" />
        </div>
        <div>
            <input type="password" placeholder="Password" required="" id="password" name="password" />
        </div>
        <div>
            <input type="submit" value="Log in"  />

        </div>
    </form><!-- form -->

Update 2 hello.html

<html lang='en'>
<head>
    <meta charset="utf-8" />
    <title>Hello</title>

</head>
{% if error %}
    {{ error }}
{% endif %}
<body>

      Hello 

</body>
</html>
