Why I can't save logging to database via NLog? - asp.net-core

Question

Why I can't save logging to database via NLog? Then I save to file is working perfectly, but to database not.
My nLog.config:
<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<targets>
<target name="alllogs" xsi:type="File" fileName="C:\Users\Artyrik\Desktop\RVT\RVT_Administrator\RVT_Administrator\file.txt" />
<target name="database" xsi:type="Database" connectionString="Server=DESKTOP-GDI15RS\\SQLEXPRESS;Database=RVTLogs;Trusted_Connection=True;MultipleActiveResultSets=true"
commandText="insert into dbo.Administrator (
MachineName, Logged, Level, Message,
Logger, Callsite, Exception
) values (
#MachineName, #Logged, #Level, #Message,
#Logger, #Callsite, #Exception
);">
<parameter name="#MachineName" layout="${machinename}" />
<parameter name="#Logged" layout="${date}" />
<parameter name="#Level" layout="${level}" />
<parameter name="#Message" layout="${message}" />
<parameter name="#Logger" layout="${logger}" />
<parameter name="#Callsite" layout="${callsite}" />
<parameter name="#Exception" layout="${exception:tostring}" />
</target>
</targets>
<rules>
<!--<logger name="Admin" minlevel="Trace" writeTo="alllogs" />
<logger name="User" minlevel="Trace" writeTo="alllogs" />-->
<logger name="AdminLog" minlevel="Trace" writeTo="database" />
</rules>
</nlog>
Implement in a Class:
```
private static Logger _nLog = LogManager.GetLogger("AdminLog");
_nLog.Info(data.IP + " tried to auth.");```

You need to add internalLogFile parameter to your nlog tag. You will have an internal log and see what is wrong with your configuration if an error occured :
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
autoReload="true"
internalLogLevel="Info"
internalLogFile="c:\temp\internal-nlog.txt">
