Not able to connect

Good morning, I have been trying to connect and I get the following error, not sure what it means

CDMUtil.ConsoleApp[0] at Microsoft.Data.Common.DbConnectionOptions.ParseInternal(Dictionary2 parsetable, String connectionString, Boolean buildChain, Dictionary2 synonyms, Boolean firstKey) at Microsoft.Data.Common.DbConnectionOptions..ctor(String connectionString, Dictionary2 synonyms) at Microsoft.Data.SqlClient.SqlConnectionString..ctor(String connectionString) at Microsoft.Data.SqlClient.SqlConnectionFactory.CreateConnectionOptions(String connectionString, DbConnectionOptions previous) at Microsoft.Data.ProviderBase.DbConnectionFactory.GetConnectionPoolGroup(DbConnectionPoolKey key, DbConnectionPoolGroupOptions poolOptions, DbConnectionOptions& userConnectionOptions) at Microsoft.Data.SqlClient.SqlConnection.ConnectionString_Set(DbConnectionPoolKey key) at Microsoft.Data.SqlClient.SqlConnection.set_ConnectionString(String value) at Microsoft.Data.SqlClient.SqlConnection..ctor(String connectionString) at CDMUtil.SQL.SQLHandler.executeSQLQuery(String query) at CDMUtil.SQL.SQLHandler.retrieveViewDependencies(String entityName) at CDMUtil.Manifest.ManifestReader.updateViewDependencies(String entityName, String viewDefinition, List1 metadata, AppConfigurations configurations, ILogger logger) at CDMUtil.Manifest.ManifestReader.manifestToSQLMetadata(AppConfigurations c, List`1 metadataList, ILogger logger, String parentFolder)

Start with the stack trace at CDMUtil.SQL.SQLHandler.executeSQLQuery and the Microsoft.Data.SqlClient connection-string parsing calls. Reproduce the connection attempt and inspect the connection configuration used by retrieveViewDependencies; done means identifying the invalid or missing connection setting and documenting a verified connection attempt.
