What breaks if you block it
Block with care
Blocking this host can interrupt OpenSEO integrations that depend on it.
What breaks if you block it
- An app or assistant using app.openseo.so may fail to connect.
- Tasks depending on this integration may stop until the connection is restored.
With Kilobat Pro and the network filter, you can block a host for every app or for one app: in Connections, select a connection and choose Block. Apple’s own services are never blocked by Kilobat’s Protection lists.
Notes
A service can use other hostnames too. Blocking this host alone does not necessarily block every feature.
If the connection is unexpected, inspect the originating process and review its configured integrations.
