Hi team!
After successfully deploying, I get this error which I don’t seem to be able to fix (probably due to lack of rails knowledge).
I tried to add
config.hosts << “knhchris.fly.dev”
to the production.rb but still same error.
Would anyone be able to help please?
To allow requests to knhchris.fly.dev make sure it is a valid hostname (containing only numbers, letters, dashes and dots), then add the following to your environment configuration:
config.hosts << "knhchris.fly.dev"
