c# - Cannot write log to LogEntries from Azure Web App -

from inside asp.net web api application (version 5) trying send logs logentries cannot. same code , configuration, can send logs localhost.

this code using send logs (with nlog:)

private static logger log = logmanager.getcurrentclasslogger();  public static void logstring(string message) {     log.error(builder.tostring()); } 

this web.config configuration:

<appsettings>     <add key="logentries.token" value="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" /> </appsettings>  <nlog> <extensions>   <add assembly="logentriesnlog" /> </extensions> <targets>   <target name="logentries" type="logentries" debug="true" httpput="false" ssl="false" layout="${date:format=ddd mmm dd} ${time:format=hh:mm:ss} ${date:format=zzz yyyy} ${logger} : ${level}, ${message}" /> </targets> <rules>   <logger name="*" minlevel="debug" appendto="logentries" /> </rules> 

when run code on production azure web app, not see logs on logentries console. when run on localhost, runs successfully.

i tried make simple http request webrequest class google.com , 200 server on azure. think azure app can access internet cannot / not access logentries servers reason.

how can diagnose this?
