Running the pre-call test resulted in an error being displayed in the "Connecting to Other Participants" section of the pre-call test.
An alternative solution is to use another network - such as a 4G phone/mobile broadband connection to connect to your call.
Attempted to join a call and been presented with a 'There is an issue with your connection' message.
Not connected to the Internet
If your Internet connection has dropped out, or for some other reason become unavailable, then Video Call will detect this and display this notification. In this instance, restoring your connection will result in this error automatically resolving itself.
If you are travelling while using Video Call, you may experience this error when your mobile device changes between cellular towers, or when entering areas of low/no service (such as tunnels).
When a drop out occurs, Video Call immediately starts watching for the restoration of your connection. If your Internet connection is restored, Video Call will pick this up and restore your call.
Joined a call and have been presented with the 'Signaller Connectivity' warning?
Video Call uses a technology known as WebSockets for our call orchestration. While a standard, and highly prevalent web technology, some network architectures include proxies and/or firewalls that can block the necessary connection upgrades required for WebSockets to work, and result in an inability to connect to our Video Call infrastructure.
You can test to see if this may be a potential issue for you using https://websocketstest.com/
If you are behind a proxy or firewall that is restricting WebSockets, this is something that may require the intervention of your network's administrator to enable.
An alternative solution is to use an alternative network - such as a 4G phone/mobile broadband connection to connect to your call.
Similar to the above section, some Antivirus software can interfere with the establishment of a WebSockets connection.
If you are experiencing interference from your Antivirus Software, you may be able to add an exception for videocall sites (https://*. vcc.healthdirect.org.au) for your Antivirus to allow WebSockets to work.
If you are within a corporate network, this may require the assistance of your network administrator.
Attempted to join a call the other participant never appears in your video room?
Analysis: you are not connecting to the Coviu signalling server, which is connecting up the endpoints to each other via Websockets.
Recommended option: Please run a pre-call test at http://vcc.healthdirect.org.au/precall. The results will advise you of actions to take to optimise your network connectivity.
For many networks, allowing NAT egress to UDP port 3478 on the relay server (vcct.healthdirect.org.au) will provide low latency with little overhead. This should require only a minor, low-risk change to your network configuration.
