Rank 2: Process
This used to work and then at some point it stopped. One thing that happened in that time was moving my application to Vercel. I have read on another thread that someone else had a similar issue which ended up being related to their SSL certificates.
My application uses subdomain, and previously when this was working I had manually configured the SSL details with Let'sEncrypt - but Vercel now manages this.
Another thing I did was cloned the droplet my AppWrite instance was running on and then upgraded from 1.4 to 1.6 -> whch I'm now running on the new cloned droplet with a different IP
I have verified that my .env file in appwrite has the same details as SendGrid and that I'm trying to put into AppWrite (selfhosted v1.6).
SendGrid works to send normal email via my application using the same apikey.
