Connection Error - SQL Server 2005

Hello guys;

I have a problem with prometheus connection error with my SQL Server 2005 instances.

The error that appears in the prometheus log is this…
I0609 13:48:51.560255 6 promhttp.go:38] Error gathering metrics: [from Gatherer #1] Login error: EOF
I0609 13:49:21.536107 6 promhttp.go:38] Error gathering metrics: [from Gatherer #1] Login error: EOF
I0609 13:49:51.527936 6 promhttp.go:38] Error gathering metrics: [from Gatherer #1] Login error: read tcp PrometheusIP:43208->MySQLIP:1433: read: connection reset
On other SQL database servers above 2005 it is working correctly.

What could be causing this problem?
