Hi everyone, I have an issue launching prefect server from an EC2 instance, when I access the dashboard, it won’t load anything. Anyone had this issue before?

Does the API connection indicator in the top right show that you are successfully connected?

Hi Michael, checked the API connection, it isn’t “Couldn’t connect to Prefect Server at http://localhost:4200/graphql”

Yep! So you’ll need to update the UI to point to the apollo deployment on your EC2 instance

you mean this one?

Yep!

Ok, so what is there to change, I have not made any changes to the default

config.toml

The box where it says “Prefect Server GraphQL endpoint”

ok ok, got it, let me try that out

When you’re using the UI, your browser is sending requests directly to the API (pretty standard modern javascript) so your browser is trying to hit the api at

localhost:4200/graphql

but the api is running on an EC2 instance not locally

Thanks! It’s odd, because as part of my initial user-data script for the instance, I changed the toml so that the actual EC2 instance host is set for graphql

Do you also update the

apollo_url

in the config?

yep, exactly that line. Actually, I’m only changing that line.

Wonderful!

Thanks for the super fast help!!
