I modified my CNAME records as described in this link https://devcenter.heroku.com/articles/custom-domains . The redirect itself works, the problem is in Chrome (and I assume that other browsers). This gives me a phishing alert.
This is probably not the site you are looking for!
You tried to contact app.grewpr.com, but instead you really reached a server that identified itself as * .herokuapp.com. This may be due to a misconfiguration on the server or something more serious. An attacker on your network might try to force you to visit a fake (and potentially dangerous) version of app.grewpr.com.
You should not continue, especially if you have never seen this warning before for this site.
How can I fix this error? It also puts a red line through the https lock.
