New to D&D player looking for Free to play Campaign to learn game

Hello, I am new to D&D and have wanted to play for a while now. I am looking to play in a starting campaign designed to teach a new player how to play. I am interested low to mid roleplay with more focus more on action and adventure. I have created a Halfing Rouge here on Beyond that I would like to try. I am not sure what server that I would need but could sign up for pretty much any of them in order to play, I have Discord at this time. I would be looking for a bi-monthly short of game hopefully on Thursday nights starting at about 6:30pm MST. Please reach out and let me know if you can help. Thanks
