I came across on MERN stack web app which is deploy on Digital Ocean Droplet.
It has some SMTP credential issues, i found the right credential , test in my local host. It's working smoothly. When I make the same changing in my digital ocean droplet server, it's throwing ERROR 504 GATEWAY_TIMEOUT 'api.link/'.
I have .env file , where I updated SMTP credential
How can i fix this issues?
