Can no longer connect in lan only mode

I’ve had no issues with my printer since I got it in december.
Today, it will not connect to bambu studio in lan only mode. I enter the ip address and access code and it does not connect.
Can anyone help, please?
Thank you

Can you ping the IP from that computer?

Yes. I just did and it did ping. tks

Belarc also shows it live and this address

Physical Address 3C:84:27:FA:15:00

Has anyone had a similar problem in the last few days?

Streaming function error. Please check the network and try again. You can restart or update the printer if , the issue persists.

I found the issue. Somehow, the firewall permissions in windows 11 were changed and bambu studio was not allowed access to my private network. I changed that this morning and bambu studio can see the printer again.
Tks for the help.
