    Zabbix doesnt connect to MSSQL by ODBC, although isql -v works

    Greetings,

    I feel like i'm stucked trying to deploy MSSQL by ODBC template in my Zabbix. I've been following different tutorials and even searched for help here in the forum but nothing seems to have fixed the problem.

    So I have the following SO with Zabbix already working fine:

    NAME="AlmaLinux"
    VERSION="9.2 (Turquoise Kodkod)"
    ID="almalinux"
    ID_LIKE="rhel centos fedora"
    VERSION_ID="9.2"
    PLATFORM_ID="platform:el9"


    I've followed the official documentation from Zabbix to deploy and configure MSSQL by ODBC: https://www.zabbix.com/integrations/mssql

    However when I go to Zabbix to see if I'm monitoring the alerts I get the following error:

    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]


    The DSN, username and password is set in the macros. The SQL user logins correctly to MSSQL and I manage to connect from the zabbix server using isql -V




    Telnet also works

    I've tested windows odbc from a computer that is in the same network and it connects correctly (message is in spanish)

    So at this point I dont understand where's the problem, looks like the connection is fine but Zabbix somehow cant connect.
    Zabbix version is 6.4, I've tried also with odbc version 18, and also using the TDSFree driver or whatever is called but I have the same problem.

    Any ideas?

    Best regards​​

    Hi,

    the same error I have.
    I did a lot of check all parts of configs and... config of Linux might be tricky. Did You check SELinux status?
    Run command sestatus and share info.

    Then You can read:
