# Bug Report `fly check-resource` fails with a `405` error if the concourse URL protocol is `http`. Changing to `https` fixes the problem. ``` error: Unexpected Response Status: 405 Method Not Allowed Body: Method Not Allowed ``` The behaviour is okay since https should be encouraged, but the fly error message should be improved. * Concourse version: 3.6.0 * Deployment type kubernetes * Infrastructure/IaaS: aws * Browser (if applicable): - * Did this used to work? ???
