I try to preview a local replica of an application in the local web browser. For this, I choose Actions → Preview in Web Browser when the app is selection in the workspace. The result is ‘Navigation to the webpage was canceled’ and the log shows the following entry:
PM HTTP Server: Error - Unable to Bind port 80, port may be in use or user needs net_privaddr privilege
I used “netstat -na” to verify that port 80 is not in use. I checked, using Fport, that port 80 is open. Finally, I even installed Xampp to verify that it is able to bind to port 80 and displays a webpage. When Xampp was running, Notes would also emit the above error message (this time I could understand it).
Any ideas what this could be? I have just installed Notes 8.5 with Designer/Administrator afresh and the problem persists.
Evan, Steve, thanks a lot for your supportive reply.
I indeed disabled the firewall and disabled all startup items via msconfig, too. Also, I did not change my host file.
A few minutes ago I have just deinstalled AVG Free 8 and - surprise, surprise - everything works again. I did not know that AVG Free contains firewalling features. Another lesson learned…
…for posting the solution. I did suspect AVG on my machine but couldn’t get it to tell me what it was silently rejecting. AVG is a bit of a pain I’m finding. The realtime scanning of all files used makes Designer 8.5 practically halt.
