My session won't start and/or I see a connection timeout

When joining someone's screen, Drovio prompts you with the error "the connection has timed out". In this article, you will find useful information about this issue.

Why do I get this error and how to fix it?

This error can be caused by a wide variety of factors, all generally related to your network. It can just be a temporary network interruption or a more specific issue concerning your network configuration.

📶 You are facing a temporary network interruption

It is possible that your Internet connection has been interrupted while Drovio was negotiating the connection between your teammate and you. Please ensure that you are still connected to Internet and tell your teammate to invite you once again.

🔑 You are using Drovio behind a proxy

In this case, you have to configure some proxy settings in Drovio:
Click on the settings button located at the top-right corner of the app
Select Preferences
Click on the Network tab
Enable proxy configuration by checking the Enable checkbox
Fill the Hostname field
If your proxy requires authentication, fill the Username and Password fields
Restart Drovio

⛔️ A firewall does block some required ports or you have NAT issues

As a first step, you can try to temporary turn off your operating system's firewall and see if it does solve the problem. Then turn it on again and add rules to it, as explained below.

Drovio relies on a peer-to-peer architecture. When a P2P connection is established between one of your teammate and you, audio, video and data streams are transported over UDP ports (any ports between 1024 to 65535). If a firewall is active and some ports are blocked, Drovio can be unable to establish P2P connections.

Up to 20% of P2P connections may fail due to restrictive firewall or NAT configurations. To handle that, we use relay servers, acting like gateways. Your sessions are secured and your privacy is respected, we cannot decrypt anything from these servers, even if we wanted to. They just forward the data. Those relay servers require at the very least TCP port 443 to be opened from client to the Internet and firewall configured to actually accept non-HTTPS packets.

For the best possible experience with Drovio, we recommend opening UDP ports from 1024 to 65535 between participants.
