Remote connections stopped working

[Andyman]

Connections from a web browser or the windows app to BI are refused. They had been working for months.

I bounced the PC running BI and checked BI. It is recording normally.

The DNS resolves correctly. The PC runs Windows 10.

Are some settings updated automatically in Windows or BI? Could it have been hacked?

What should be checked?
