[quote user="qilin"][quote user="Graham"] Hmm. Later versions of Synapse use Cheyenne web server on port 8002. Can you check in task manager if Cheyenne is running ( it should be in system tray as icon ). Perhaps you're blocking it? Try browssing to http://localhost:8002 and see if you get a 404 ... [/quote] Cheyenne is running on task bar. I don't think I am blocking it since it was working before this last client. When I change the port to 8001, page can display correctly. http://localhost:8002 gives "Internet Explorer cannot display the webpage" message, not 404 [/quote]That message means that Cheyenne is not working as a web server. Please check to make sure it is not being blocked. Port 8001 is the old web server which is still running .. I'm keeping it for other purposes so that's why it still works.
