If you experience issues with the video transmission either through WiFi or cellular data, try the following steps:
- Check if the following ports are open on your network, as a firewall on that network could be blocking some ports that our app needs. This often happens on public WiFis (such as hotel WiFi). Our app needs the following ports: TCP port 5222 for audio, TCP port 443 for the video. In addition, the app also requires these ports for the video: UDP port 3478, UDP ports 1025 - 65535 (media ports). A network administrator or cellular data provider should assist you with this issue.
- Make sure both devices are connected to a fast internet connection (at least 1 MB/s).
- If the video issue appears on a specific device, contact our support team at firstname.lastname@example.org with device specifications (types of devices, operating systems, version of the operating systems). Our support team is ready to help.
