  • Hi,

    According your description, the issue is related to the Skype for Business Front End server could not connect the Back End server.

    Which type do you use for the SQL high available, AwlaysOn group or mirror?

    Based on the current status, please first check the SQL server is working well.

    And there are no missing logins under “Security Logins”.

    You could refer to this link to review the configuration:
