#43 but on v1.4.2. Game restart fixes it, relogging or the refresh button will not.

I cannot reproduce this. Describe your exact steps.

1. Set up a server with online-mode: true, enforce-secure-profile: true
2. Enter the server, confirm the prompt and check the checkbox
3. Verify the icon in chat (red)
4. Leave the server
5. Set the server to online-mode: false, restart it
6. Join the server
7. Verify the icon in chat (should be yellow but is red)

I've done the same steps as you and icon is yellow in my case after all this, just as it should be. Did you do your tests with vanilla server?

Yes, a vanilla 1.19.1-pre3 server.

Then I really have no idea what's happening in your instance. I noticed a small potential issue in my state management that might arise when you get disconnected by server instead of leaving normally, but from your words that's not your case.

Anyways, try again in v1.4.3, maybe that's somehow related after all. Also test the cases for disabling online-mode and enforce-secure-profile separately.

Seems to work now.
