The problem has been resolved.  My server hosting company provides
an interface to make changes on the firewall, so being a Windows

had turned the Windows Defender firewall on for public networks, so
it was conflicting with the firewall that we use, and that was
causing the problem.
Glad you got your problem resolved.

Based upon the error messages you reported, you had two separate issues:

1. Unable to obtain connection: Cannot create PoolableConnectionFactory (Login failed for user 'sa'. ClientConnectionId: . . .

This indicates that your application was unable to reach your database.

2. NS_ERROR_NET_TIMEOUT

This indicates that your clients cannot reach your application, and definitely points to a firewall issue. Given that the firewall fix appears to have resolved the database issue as well, that was likely to have been firewall-related as well.
