I deployed this template:

https://railway.com/deploy/5tBOUn

at first didn't worked, I tried to search and found a thread that helped:
https://station.railway.com/questions/error-application-failed-to-respond-t-2178d377

so I added HOST=0.0.0.0 to environment variables in both (view and builder)
after that I could see the login page

but still got error while trying to login

Its set hostinger SMTP "smtp.hostinger.com" paid mail server on port 465 with secure=true, I've already checked and still all working good on my smtp...

I tried secure false but not success
