Question

i am getting this error when i try to send mails via sendgrid in laravel 6:

Failed to authenticate on SMTP server with username "apikey" using 2 possible authenticators. Authenticator LOGIN returned Expected response code 250

my .env:

MAIL_DRIVER=smtp
MAIL_HOST=smtp.sendgrid.net
MAIL_PORT=587
MAIL_USERNAME=apikey
MAIL_PASSWORD=***** (my key copied from sendgrid)
MAIL_ENCRYPTION=tls

Answer 1

I had this same problem and I solved it by encoding the APIKEY in Base64.
