I have a MariaDB server running in AWS. I have enabled firewall rule for 3306 in the running instance and when I deploy the golang app in Heroku, I am able to get the API responses from the deployed heroku app. But, when I deploy the same golang app in fly.io, I am not able to get the API results from fly.io. Please help me on this.
Dockerfile:
FROM golang:1.18 AS builder
RUN mkdir /app
ADD . /app
WORKDIR /app
RUN CGO_ENABLED=0 GOOS=linux go build -o app cmd/server/main.go
FROM alpine:latest AS production

CMD ["./app"]
