WebApp rejecting connection attempt

I have deployed a registration Xojo web app that has been working beautifully so far. In the first few hours of being announced it has had over 70 successful registrations.

Then today I have one end user who has tried using FireFox and Chrome but gets rejected. I have not found out yet what platform he is using and if he is behind a firewall.

The web app is listening on port 8881. I know that he is getting through on port 80 as the address we have given out is to our database server which is on the same machine as the web app and listening on port 80. It redirects the initial request to port 8881 and the web app takes over from there.

The rejection messasge from Chrome reads…

I exed out the actual address above. Not sure if it means anything but this error message does not include the port which would have been included by the redirect from the database server, ie xxx.xxx.hawaii.edu:8881

FireFox on the other hand says…

[quote]“Firefox can’t establish a connection to the server at xxx.xxx.hawaii.edu:8881.
The site could be temporarily unavailable or too busy. Try again in a few moments.”[/quote]

Any ideas as to why the rejection? Is it in fact the web app that is rejecting the connection? Our Firewall? His Firewall? If ours why only him.

Thanks for any help.

How are you doing the redirect?

The database server is a 4th Dimension database which has a built in web server and language set. So I am not sure how the web server does it’s thing. The 4D command is WEB SEND HTTP REDIRECT and it looks like this…

WEB SEND HTTP REDIRECT(“http://xxx.xxx.hawaii.edu:8881”)

Since posting this to the forum I have learned the the end user is on the University of Hawaii wireless network. I have been told that the problem may be that the wirelss networked is really locked down tight and he will probably not have an issue if he uses a wired connection to the UH network. Have not heard back from him since I suggested he use a wired connection or go outside the UH network.

Chances are their firewall is closed to 8881.

If they’re locked down, they may not be allowed to connect to http services on anything besides port 80 or 443. There may also be a proxy involved that adds more restrictions.
