The issue is that the invite emails have stopped working suddenly.
I am not using any third party service for mail and is using the mails sent through command line. Everything worked for months but not suddenly, the invites are failing with the message:
Error sending email: Failed to send email. Please check your email settings and resend the invitation.
Could someone guide me in understanding the source of the error and fix it?
In the logs (ghost logs), I do not see any error message related to this.
