Question:

My listeners can't send a request. it will be display a error message 803.

Your request failed. Reason given: Unable to connect to xxx.xxx.xxx.xxx:1221. Station might be offline, or connection is being blocked. (Err#: 803)

Note: xxx.xxx.xxx.xxx will be an IP address.

Answer:

The error message is self explanatory. Possible reasons for this error are;

1. IP address is not static and has changed since the configuration was made. We suggest using a dynamic DNS service such as No-IP.com to assign a static host name so if your IP is reassigned on your network the service will report your new IP.

2. Make sure that port 1221 is open on your firewall/NAT/router. Goto [1] and enter port 1221 and click Check, if an error is returned then your network still needs configuring.

3. Make sure that if you are behind a router/nat/firewall with DHCP enabled that your private IP address has not changed and your firewall is sending the requests to the wrong private IP address.

4. Unless you are only trying to use on your private network the use of local/private IP addresses should not be displayed in the error message, or just on your local system only your localhost IP 127.0.0.1. If it is be sure to change the config.php file and upload to your server;

$sam["host"] = "localhost"; //The IP address of the machine SAM is running on (DO NOT use a local IP address like 127.0.0.1 or 192.x.x.x)

change to;

$sam["host"] = "your.iporhostname.goes.here"; //The IP address of the machine SAM is running on (DO NOT use a local IP address like 127.0.0.1 or 192.x.x.x)

For samHTMweb users change the line in your _config.html file;

<!--VAL(samhost,"$host$")--> 

to;

<!--VAL(samhost,"your.iporhostname.goes.here")-->
