It was nice to meet you?
"It was nice to meet you" is correct.
This is said at the end of the conversation. At the time you are introduced you can say, "it is nice to meet you" or "I am glad to meet you". I would not say "It felt nice to meet you".
Nor would any other native speaker.I would not say "It felt nice to meet you".
A couple of other variations that are sometimes used are:
"It was nice meeting you."
"It was nice to have met you."
Please understand I by no means want to argue or refute your views or statements, I dont think I have knowledge and skills to do so. I am no match for you, still as a thinking language enthusiast, I would like to put my point across and would like you to clarifying without going bananas...
I think this is the way I learn and I am able to extract the maximum out of stalwarts like you and develop a better understanding of the concepts of language.
