Hello there,
If you are moving from the old Dynamics NAV days over the new Business Central Version 19 & above,
you have encountered a bit of challenge getting the baby to display in the web browser.
In the old days you only needed to install NAV client. Then any new instances would be created via Microsoft Dynamics Management client.
This time you need to configure Business Central Server
You also Configure Business Central Web sever & point it to the BC server
Use the following links to setup the web server
Good luck
