Issue with SendGrid

danielunited

I'm having problems sending emails through SendGrid. I verified my domain + identity, but can't send emails from Flarum.

Port 587 with TLS works fine 🤷
clarkwinkelmann

That problem must be specific to your server/hosting.
Either a firewall or your hosting is blocking that particular hostname, IP or port. If you are not able to find where to unblock it, you should probably contact your hosting support.
Did it work previously on the same server?

clarkwinkelmann That's probably the issue. Thanks.
