Invalid URI: The hostname could not be parsed
I was having few hours of work-a-round when I was trying to Set-up/Deploy the DotNetNuke Environment at my local pc.
I restore the DB Backup of DNN, copied the source at my local pc drive and configured the Virtual Directory for the application.
I also made the changes in Web.Config file; that is Connection String related changes.
As we have to specify the Portal Alias in PortalAlias Table in DBB DataBase, I defined it as localhost/dnnapp (you need to make sure that this would be the first PortalAlias entry, like localhost/dnnapp; and Do not add the http:// part.
After all these settings, I hopefully tried to access the application with "http://localhost/dnnapp
" URL; but I got one (it seemed to me a common error) error, "Invalid URI: The hostname could not be parsed". I again checked my DataBase Settings (UserID, pwd, PortalAlias etc.) , Web.Config Settings; but didn't get any success; except some variation in error message; that is "Page cannot be displayed". But the most common error I was having is of "Invalid URL: The hostname could not be parsed" only. Lastly, I attempted to stop IIS and start it again, and it worked finally. I am not sure that this is the solution of this error message but it worked for me.
