Make integration Error 535

Hello there,

Recently I created a short automation that uses a webhook to get a informations from a chatbot, send it to GPT to create an automated mail and than send this mail to the user.

Unfortunately I get the following error:
535: EAUTH: Invalid login: 535-5.7.8 Username and Password not accepted. Learn more at

Has anyone encoutered this error and if so, how did you fix it?
Help is much appreciated!

Thank you all, and have a great day.
Best regards,

Please delete your Gmail connection, and then take screenshots of the steps you used to add a new Gmail connection.

I re-did the connection as described in the video, it seems to work now. I don’t know why, but I won’t complain!

Thank you very much for your answer!!
