I tried building ODK Central on an AWS EC2 instance by following the Setting up ODK Central Docs. But I am getting build failure. Here is the error message. Step 5/13 : COPY server/package\*.json ./ COPY failed: no source files were specified ERROR: Service 'service' failed to build : Build failed Please help. ---

Welcome to the forum @sudhir2016 and thanks for adding your profile picture. It helps build community! We're glad you're here. When you get a chance, please [introduce yourself on this forum thread](https://forum.getodk.org/t/-/6671). What AWS AMI and what EC2 size are you using? Also, it will be hard to troubleshoot without knowing all the steps taken before that particular error message and a more complete log. Are you able to try and again and note down each step you take as you go? ---

Thanks Dan. I have introduced myself. As suggested in the docs I used t2.micro and Ubuntu Server 20.04 LTS. I also tried to follow all the steps to build as per the doc. However I will try again and provide a more details. ---

I tried again and was able to build. I guess I missed apt upgrade before starting. Now I am struggling to connect to Central from Chrome browser. Quick question on this. I just provided public IP4 address in env file. Will this work. ---

I am not sure but can provide some steps for debugging. What happens when you plug that IP into a browser? Can you get a response when you ping it? You'll eventually want to go through Route 53 and setup a domain and such, for security reasons. I have fairly limited experience doing that but here is the AWS guide on the topic [https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-to-ec2-instance.html](https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-to-ec2-instance.html) ---

Which is why we have it in the documentation at [https://docs.getodk.org/central-install-digital-ocean/#getting-a-web-address-domain-name](https://docs.getodk.org/central-install-digital-ocean/#getting-a-web-address-domain-name) and have a comment in the the env file that says "Use fully qualified domain names". ---

Thank you Yanokwa. So there is no temporary work around like setting Domain=Local and SQL\_TYPE=Selfsign and using http instead of https in browser just for testing. Or maybe something else.
