I'm attempting to configure VS Code's InterSystems Server Manager to establish a connection to an IRIS for Health server. It has a standalone CSP gateway running on an Apache server with TLS enabled. The port for all IRIS api and browser traffic is 443.
I've configured the webServer section's host, port, and variations on pathPrefix (including no pathPrefix entry), and have the correct user ID set. The password is stored in the server keychain.
The connection simply fails with "Server could not be reached." Nothing in the Output or Problems tabs.
