Enable WebSockets on your environment

The Neatro application requires WebSocket connections. Here’s how to ensure they are properly enabled.

The Neatro application — specifically Retrospectives and Team Radar activities — requires WebSocket connections to function correctly.

If you are able to access the dashboard and member pages, but cannot open activities, your network may not support WebSockets.

Test your connection

To test whether your connection supports WebSockets, please open the following website: https://websocketstest.com/

If WebSockets are detected, you will see a confirmation message.

If the result indicates that WebSockets are not supported, it is likely that something in your network is blocking them.

Troubleshooting steps

If WebSockets are not detected, try the following:

  • Use a different network connection

  • Use a VPN

  • If you are using a corporate network, contact your network administrator and ask them to enable WebSocket connections on ports 80 and 443 (SSL). These ports may be closed or filtered within your corporate network for security reasons. To establish a connection, these ports must be open for Neatro domains and addresses (see the “If you use a Firewall” section below).

If WebSockets are correctly detected but you are still experiencing connection issues, please contact Neatro support at support@neatro.io.

If you use a Firewall

Please allowlist the following domains and subdomains:

  • neatro.io*

  • *.neatro.io

  • neatro.service.signalr.net

If you use a proxy

Please ensure that Neatro traffic is excluded (bypassed) from restrictive proxy rules. The following configuration requirements apply:

  • The proxy server must support WebSocket connections (HTTP/2).

  • The proxy HTTP version should be set to 1.1.

  • Source port: 80 (used to redirect HTTP traffic to HTTPS; blocking port 80 is not recommended).

  • Destination port: 443 (SSL) for HTTPS traffic.

  • Protocol: HTTPS

  • TLS version: 1.2

  • The timeout value on the proxy server should be extended. Some systems default to 60–90 seconds; we recommend increasing it to 120–180 seconds.

  • The proxy server must not truncate request or response headers. Please verify that the Upgrade and Connection headers are properly forwarded by the proxy.
