Bad Request - Invalid Hostname IIS7

Question

When I try to hit my web app on port 8080 I get the following error

Bad Request - Invalid Hostname
HTTP Error 400. The request hostname is inval

Answer 1

Did you check the binding is IIS? (inetmgr.exe) It may not be registered to accept all hostnames on 8080.

For example, if you set it up for mysite.com:8080 and hit it at localhost:8080, IIS will get the request but not have a hostname binding to match so it rejects.

Outside of that, you should check the IIS logs (C:\inetpub\logs\wmsvc#) on the server and see if you are seeing your request. Then you'll know if its a problem on your client or on the server itself.
