Prestashop 1.7.8.2 e-mail problem

[xtelefonx]

Hello,
I am having a non-typical problem with emails. From the website you can send messages. If the customer places an order, the message is also sent to the customer. However, the message is no longer going to me, the same in the back office I want to send a test message, Failed to authenticate on SMTP server with username "my_email_address" using 3 possible authenticators. Authenticator LOGIN returned Expected response code 235 but got code "535", with message "535-5.7.8 Username and Password not accepted. Learn more at 535 5.7.8 https://support.google.com/mail/?p= BadCredentials k16sm462250lfg.240 - gsmtp ". Authenticator PLAIN returned Expected response code 235 but got code "535", with message "535-5.7.8 Username and Password not accepted. Learn more at 535 5.7.8 https://support.google.com/mail/?p= BadCredentials k16sm462250lfg.240 - gsmtp ". Authenticator XOAUTH2 returned Expected response code 250 but got code "535", with message "535-5.7.8 Username and Password not accepted. Learn more at 535 5.7.8 https://support.google.com/mail/?p= BadCredentials k16sm462250lfg.240 - gsmtp ". Only if it was a password error or a wrong user, would it also be a problem sending messages from the store, and it works. Maybe someone is able to suggest where to look for a solution?

I had the same problem. My browser was auto filling the password field. Try, remove autofill from browser settings.
