Troubleshooting Director Connection Issues
- Selecting Advance in Megaphone Director has no effect, or advances the playlist slowly
- Megaphone Director displays a "poor-connection warning," such as the following:
How to Fix a Poor Connection
Typically, the "poor-network warning" in Megaphone Director is caused by one of the following:
- a slow network connection on the specific computer running Megaphone
- slow application performance on the specific computer running Megaphone
- a firewall or limitation imposed by the network on the computer running Megaphone
To determine the exact cause of a slow network connection, follow these steps:
- Try connecting the computer to another network, such as a home WIFI connection, a WIFI connection at a cafe, or a "personal hotspot" (tether) supplied by a mobile device such as a smart phone. If possible, use a wired LAN connection rather than a WIFI connection.
If network problems do not occur on a different network, then the cause of the problem lies in the network to which the computer was originally connected—not in the computer itself, nor in Megaphone.
To identify the specific issue causing the problem, connect the computer to the network where the problem initially occurred and proceed to Step 2.
- On the computer experiencing the symptoms, close all applications and all browser tabs and windows, then restart the computer. After the computer restarts, proceed to Step 3.
- In a new web browser window, with no other applications open on the computer, open Megaphone Director (at http://studio.megaphonetv.com/).
- Click Director's top panel, to the left of the current playlist.
- On your computer's keyboard, open the Megaphone Debugging panel by pressing the 'Y' key.
- On the right-side of the Megaphone Debugging panel, locate Connection Type, as shown here:
If Connection Type reads SECURE_SOCKET, proceed to Step 7. If Connection Type reads SECURE_HTTP, follow these steps:
- Reload Megaphone Studio by refreshing your web browser.
- Perform Steps 4 through 6.
- If Connection Type still reads SECURE_HTTP, secure socket communications are blocked on your network. To resolve the problem, ask your network administrator to configure the network as described under Network Configuration - For Network Administrators.
- On the right-side of the Megaphone Debugging panel, locate FPS, as shown here:
If FPS consistently shows a number over 45, proceed to Step 8. If FPS consistently shows a number under 45, your computer is running slowly enough to affect Megaphone performance. Ensure that you have closed all applications and restarted your computer, and have Megaphone Studio running in a single browser tab (as described in step 1). If FPS still consistently shows a number under 45, your computer may not be fast enough to run Megaphone. Try running Megaphone on a different computer.
- On the right-side of the Megaphone Debugging panel, locate Ping, as shown here:
If Ping consistently shows a number under 250, your network connection should be fast enough to run Megaphone smoothly. Wait until the symptoms occur again, then follow these steps again. If Ping consistently shows a number over 250, follow these steps:
- In a new browser window, open the following website:
- Click Begin Test.
- Wait for the test to complete.
- If the Ping displayed in speedtest.net is much lower than the Ping shown in Megaphone (for example 50 at speedtest.net but 400 in Megaphone), please contact Megaphone support for a deeper investigation.
- If the Download Speed is less than 10 Mbps or the Upload Speed is less than 1 Mbps, your network connection might be too slow to run Megaphone smoothly. Please contact your network administrator and request faster network access for the computer running Megaphone.
Connection Problems Are Usually Limited to One Computer or One Network
Note that if one computer running Megaphone has a poor network connection, other computers on the same network might experience network problems, but computers on other networks will not normally be affected. For example, if the computer broadcasting Megaphone graphics to the air path is on a network named "XYZLive" and the computer used to operate Megaphone is on a different network, named "XYZControl", then slowness on the operations computer will not normally affect the broadcast computer. Different networks have different connection parameters.
Network Configuration - For Network Administrators
To achieve optimal performance, Megaphone must be run on a network that allows persistent TCP/IP, TLS secure socket communications over port 443. Network administrators should configure firewall access as follows:
- open port 443
- allow TLS on port 443
- allow long-running TCP/IP sockets over port 443
- If restricting by DNS, Megaphone socket connections will connect to servers in the *.mgaphn.com domain namespace. However, assets may be loaded over HTTP from other servers. For details, please see the Megaphone TV Networking Requirements.
