Flask Form Submit does nothing

Question

Clicking on the submit button literally does nothing. Submitting a blank form will trigger the validation for the required fields, but filling out the form as required results in the form not submitting/submit button doing nothing. The template has the CSRF_Token, Submit Button is in the form tag, and the form tag has an action attribute pointing in the right direction. Chrome doesn't bark any errors so I'm stuck on how to proceed.

What you have written looks really complicated, why not try something easy like-

@app.route("/connect",methods=['GET','POST'])
def connect():
    if request.method=='GET':
        return render_template('connect.html')
    if request.method=="POST":
        return render_template('Thankyou.html',name=request.form['name])

in you views.py and in your connect.html form just write-

<form name="connect" method="post" action="{{ url_for('connect') }}">
        <input class="t1" type="text" id="email" name="email" placeholder="Your Email ID">
        <input class="t2" type="text"  id="name" name="name" placeholder="name">
        <button class="btn btn-primary but" type="submit">Send</button>
    </form>

the final page, Thankyou.html can look like this-

<p>Thanks for contacting me, {{ name }} </p>
