"Failed to send email. Reason: Invalid login"

I’m trying to send an invitation to my brother so he can join as an administrator, but every time I send the invite, I get this error in the dashboard:

Error sending email! Error sending email: Failed to send email. Reason: Invalid login - 535 Authentication failed: The provided authorization grant is invalid, expired, or revoked. Please check your email settings and resend the invitation.

I also get these errors in my Ghost logs:

Error sending email: Failed to send email. Reason: Invalid login - 535 Authentication failed: The provided authorization grant is invalid, expired, or revoked. Please check your email settings and resend the invitation.

This is my SMTP configuration, using environment variables in my docker-compose.yml:

mail__transport: "SMTP"
mail__options__service: "Sendgrid"
mail__options__host: "smtp.sendgrid.net"
mail__options__port: 465
mail__options__secureConnection: "true"
mail__options__auth__user: "apikey"
mail__options__auth__pass: "REDACTED"
mail__from: "mail@scrapjackstudios.com"

Seems like problem with your api key… check your api key or recreate new one…

to be more sure thats the api is invalid try with your Sendgrid username & password in mail__options__auth__user & mail__options__auth__pass

Uh, shit. It worked with my real username and password. I don’t think that’s supposed to happen.

Glad it worked

5

Yeah, but I’m wondering why. It shouldn’t have without my API key.

6

By default sendgrid smtp works with accounts username & password. Your API key didn’t worked may be API key was invalid or your ip wasn’t whitelisted…

7

Yeah. I guess.

How to find the error logs?

I am not able to send “bulk emails” with correctly configured domains. Mailgun is asking for error logs.

How are you seeing logs? I’m having a ton of errors (in the UI) and I have no idea why. And I don’t have any logs to see why.
