After installing OS 15.0, (Sequoia)

[McJohn]

The Indigo remote client (2023.2.0) doesn't work anymore:

It works for me. I've been running 15.1 developer preview on a laptop (not the machine my Indigo server is on) and it works just fine.

This looks like a firewall issue. Can you run the Indigo client on the same machine that runs the Indigo server?

Thank you very much for the feedback, that's appreciated.

The Indigo client works locally perfect at the same Mac mini with Os 12.7.1 (Monterey).
And the remote Indigo client was also working perfect with Os 14, (Sonoma) to the Indigo Server.
But after the update to Sequoia the remote Indigo client no longer wants to connect to the Indigo server in the same network.

When we switch off in the Local Network Privacy settings for example Firefox, then indeed Firefox can't make a local connection into the network.
But when we switch this On again, (and restart Firefox) then it can make a local connection again.
For the Indigo client this won't work.
With the Terminal app we can make a "ping" connection to the Indigo Server, so I think it's not a Firewall issue.

It's working again.

Deleted the Indigo app and all the Indigo user preferences from the User library.
Installed the Indigo client fresh from the installer and voila! it's working again.
