EMailSender not working after making HTTP request

Hi everyone I am using forums to post for the first time so I don't know what the protocols are. I have to say I got no much knowledge in programing. I got a problem with sending gmail after making HTTP request to get weather data on my ESP8266 wemos. Before the request it sends e-mails without a problem. (This also uses Arduino Mega to send and receive serial data but that seems OK). I would appreciate if someone has time to have a look at the code. This is the link to the code: https://drive.google.com/drive/folders/1j7-a5T6ttwyh4JuLuY4QP3-fgmwadA40?usp=sharing Thank You.
