Steps to reproduce:

1. Installation of Zabbix 6.0 LTS based on installation instruction with configration:
   1. Zabbix Version: 6.0 LTS
   2. OS Distribution: Cent OS
   3. OS Version: 8 Stream
   4. Database: MySQL
   5. Web Server: Apache
2. Install template based on instructions: https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/db/mssql_odbc?at=release/6.0
3. Configure odbc driver to use Microsoft Driver
4. Add to host with MSSQL ODBC Template
5. Test connection from Zabbix server over isql is successful (isql -v Sx***.domain.local zbx_monitor password). 
6. Open Host (Sx**.domain.local) with SQL template attached in Zabbix  (Configuration->Sx**.domain.local) -> Discovery -> MSSQL by ODBC: Database discovery and click on Test button and Get Values button with error : 
7. Cannot connect to ODBC DSN: [SQL_ERROR]:[HYT00][0][[unixODBC][Microsoft][ODBC Driver 17 for SQL Server]Login timeout expired]|[08001][10013][[unixODBC][Microsoft][ODBC Driver 17 for SQL Server]TCP Provider: Error code 0x271D]|[08001][10013][[unixODBC][Microsoft][ODBC Driver 17 for SQL Server]A network-related or instance-specific error has occurred while establishin]
8. Same issue shows also with Driver 18  or with FreeTDS even isql works correctly.

Result:
Query over Zabbix ends with error even ODBC is working as i can connect to the same server over isql.

Expected:
When i tried to install Zabbix 5.0 LTS ODBC query with Get Values button was successful.
