Are you facing network related issues like not being able to see or hear other people while using Mibo? It might be the case that you are on a restricted corporate network, on a VPN or behind a firewall that is blocking connections.

You might need help from your IT department or the network administrator: please point them towards this article to configure the correct ports and whitelist the domains used by Mibo.

<aside> 👀 Your IT department or network administrator can check if their settings actually have the desired effect by going to https://getmibo.com/check. All of the checks need to pass for Mibo to work. If one more requirement is marked with a red cross, it needs to be resolved before being able to use Mibo.

Domains

Your computer needs to be able to access the following domains for Mibo to function correctly:

*.getmibo.com
*.cloudfunctions.net
*.googleapis.com
*.firebase.com
*.photonindustries.io
*.avstack.net

Ports

Mibo uses the following ports:

tcp/80
tcp/443 (non-web traffic must be allowed)
udp/3478
udp/10000

Minimum requirement

You at least need to be able to connect to the above domains on TCP port 443 and need to make sure non-web traffic is allowed on this port. If your firewall only allows web SSL traffic over TCP port 443 you won't be able to connect to Mibo.

Note: If you stop here Mibo will work, but be aware you will use extra internet bandwidth and resources from your computer. Because TCP requires you to acknowledge every bit of data received and will keep retrying data unacknowledged data, even if it's already outdated. Therefore it's strongly recommended to also allow UDP traffic as described below.

Best experience

We also recommend to make sure outgoing connections to UDP port 3478 are allowed. This port is used by a so called STUN server that helps you connect to other participants in Mibo if you are behind a firewall.

Open up UDP port 10000 for the best possible experience. This enables you to connect without extra relays in between, this removes a hop for the audio and video data to take, giving you better experience.
