It’s usually observed people quite commonly stumble upon 502 gateway error / Invalid credentials while using harness-cd-community.
502 Bad Gateway
The pods aren’t ready yet and all the deployments aren’t available
Why it happens and how to avoid it?
Once you run the command docker-compose up -d for docker based installation and helm install harness ./harness --create-namespace --namespace harness for helm based installation it takes little time for the pods to start running and deployments to get available. So make sure you run kubectl get pods -n harness , kubectl get deployments -n harness and get the following results of all the pods having status ‘Running’ and then go for the sign-up page.
kubectl get pods -n harness

Invalid Credentials
Wrong credentials or the admin user isn’t created yet using the sign-up page
At times you get redirected to sign-in page once you are done with installation, instead of the sign-up page so make sure you visit the http://localhost:7143/#/signup for helm based installation and http://localhost/#/signup for docker based installation to create the admin user to avoid getting invalid credentials on the sign-in page.
