All of a sudden this message pops up and neither users can connect the company files being on the Quickbooks server.

The company files is residing on one of the computers that also has the server app.

This is on two iMacs with the same operating system and same version of Quickbooks 2024 - V23.1.6 R7

Nothing has been changed on the system nor network. The apps were working just fine the day before.

Any help will be appreciated as now we cannot work. Thank you.
