Hi there,
I am running the tutorial for Nomad: Deploy and Update a Job | Nomad | HashiCorp Developer
The web app show Internal server error both on Mac and Linux.
Any help is appreciated.
Hey!
We would need more information about it. Could you paste your error? What step are you struggling with? Could you help us to reproduce the problem?
Thanks!
Hi there.
I’m experiencing the same problem: When following the instructions for the “Local” nomad cluster, I get an internal server error when trying to access the web app’s frontend on 127.0.0.1:5000. The tutorial works perfectly fine for AWS.
My base setup as follows:
- 2020 Apple M1, 16GB
- Homebrew 4.0.19
- Docker version 23.0.5, build bc4487a installed via homebrew/ cask but it’s Docker Desktop
- Terraform and Nomad installed from hashicorp/tap
- System firewall is off
Here’s the error log from the web app’s docker container. The redis task is running and doesn’t show any errors (unless I try connect to it via http).
