Connection issues are usually the result of a software firewall
blocking the connection. There are a couple of things you can try:
1. First, rule out the simple stuff. Make sure the Signal application
is running on your computer. Verify that the iPhone/iPod is on the
wireless network and not EDGE (the Wi-Fi icon is displayed in the
status bar). Just to double-check, verify that the device is on the
correct wireless network by tapping Settings on the home screen and
then Wi-Fi. There should be a check box next to your wireless network
name. If this looks correct, tap the blue arrow next to your wireless
network name and make note of the IP address displayed. The numeric
address shown in the Signal application window should be the same
except for the last digit.
It's also a good idea to verify that the web address is entered
exactly as it appears in the application window. Note that the last
separator between the IP address and the port number is a colon and
not another dot.
If you're using a Mac:
2. You can try connecting using the computer's Bonjour name instead of
the IP address. To do that, open System Preferences on your Mac and
click Sharing. Near the top of the screen is a message along the lines
of "Other computers can access your computer at X.local". You can use
this "X.local" name in place of the IP address. For example:
http://matts-macbook-pro.local:3569
3. If your Mac's firewall is on, Signal may need to be added as an
exception using the plus button under System Preferences > Security >
Firewall. If the firewall is set to "Allow all incoming connections"
you don't need to do anything here, but if it is set to "Set access
for specific services and applications", you'll need to add Signal
using the plus button. If the firewall is set to "Allow only essential
services" this will block Signal regardless of whether or not it is in
the exception list so either "Allow all incoming connections" or "Set
access for specific services and applications" will need to be
selected instead.
If you're using a PC:
2. If any firewall software is in use (Windows Firewall, Norton or
McAfee Internet Security, etc) verify that Signal is allowed as an
exception or has a firewall rule created for it. This is the most
common cause of connection issues.
3. Try using alternate network addresses for your computer. Signal
makes its best guess as to the primary network adaptor, but sometimes
this is not correct. To do this, go to Start > Programs > Accessories
> Command Prompt and type "ipconfig" and press enter. This command
will list all network adaptors on your system, if there are multiple
IP addresses reported here or a different IP address than is displayed
by Signal you can try using that address instead in the form of http://
x.x.x.x:3569
