Please allow access to the following addresses and exclude them from filtering and HTTPS inspection for any connection type (authenticated/unauthenticated).
Port | Protocol | Hostname | Function |
443 | WSS, HTTPS | *.senso.cloud | Services on these addresses provide front-end and back-end functionality. |
443 | WSS, HTTPS | *.service.signalr.net | Required for client communication. |
443 | WSS, HTTPS | EU Customers sensomoduleprodeu.blob.core.windows.net | Required for general storage functionality and module function |
If your firewall/filter only supports a single level of subdomain wildcarding exclude the following in addition to the above URLs:
Port | Protocol | Hostname |
443 | WSS, HTTPS | *.endpoint.senso.cloud |
443 | WSS, HTTPS | *.id.senso.cloud |
433 | WSS, HTTPS | *.servicedesk.senso.cloud |
443 | WSS, HTTPS | *.turn.senso.cloud |
How can I specify a proxy server for the senso client to use?
The senso client will make every effort to detect the correct proxy settings to use, however, it may occasionally be required to override these. To do this please follow the instructions in the article here - Manually Configure Proxy
How does the senso client route traffic?
The senso client uses 3 methods for making a secure connection between the client and the console.
METHOD 1:
The senso client tries to establish a direct peer to peer connection internally on your network. This allows your network traffic to stay local and only use your broadband line to establish the initial connection between client and the console. In theory this method should always work if you are on the same VLAN, Switch, Access Point. If the senso client is unable to make a direct peer connection, then it tries Method 2.
METHOD 2:
Where possible WebRTC will attempt to connect using host candidates, which will keep traffic local to the network. In scenarios where this is not possible; restrictive VLANs, guest networks, over the Internet, etc... then it will attempt to connect using server reflexive candidates. To do this WebRTC makes use of UDP hole punching as a method of establishing connections between clients and as such outbound UDP ports are required to be accessible, if they are not then server reflexive candidates will fail to connect and relay candidates will be attempted. However, as these are routed through the TURN server (Method 3) they will be much slower. Please see RFC 5389 for a detailed explanation of the STUN protocol - https://tools.ietf.org/html/rfc5389. This protocol is used with SIP as well, so if you have a VoIP system, you may already have exclusions in place for other STUN servers.
Port: 0-65535
Direction: Outbound
Destination: (ANY) To limit the destinations, please specify the IP addresses, subnets (host) or public IPs (srflx) of the clients you are trying to connect to.

METHOD 3:
The senso client tries to establish a connection by using the senso relay servers.
