How to turn on asynchronous logging in Slack Logger

Tell me please, how to turn on asynchronous logging in Slack?
Thanks.

Slack logging is sending requests to Slack asynchronously but you might be getting limited by your default System.Net.ServicePointManager.DefaultConnectionLimit. This can be changed by using System.Net.ServicePointManager.DefaultConnectionLimit = 100 directly or via an app.config/web.config using the following example.

<configuration>
  <system.net>
    <connectionManagement>
      <add address="*" maxconnection="100"/>
    </connectionManagement>
  </system.net>
</configuration>

Let me know if that sorts out the issue you’re having.
