Log4net appender problem

[BuTbka]

Hello!
We have successfully used Qlik Sense with the Butler and received alerts for failed tasks by following this tutorial https://butler.ptarmiganlabs.com/docs/getting-started/setup/reload-alerts/.

But a few days ago, for security reasons, all our servers were blocked from using the Internet.
After that, services using log4net appenders stopped working.
When I try to start the Qlik Sense Scheduler Service I get error 1053 that the service did not respond. In the Qlik Sense logs nothing about that and in the Windows logs "A timeout was reached (30000 milliseconds) while waiting for the Qlik Sense Scheduler Service service to connect."
When I delete the C:\ProgramData\Qlik\Sense\Scheduler\LocalLogConfig.xml file, the service starts without problems.
I am trying to use the LocalLogConfig.xml file from this article https://support.qlik.com/articles/000058553 but the result is the same.

Butbka, have you checked the firewall logs? You can find more information in the firewall logs.

Maybe there is a problem like in this article https://community.qlik.com/t5/Official-Support-Articles/An-error-occurred-Failed-to-load-connection-... ?

Yes that is the problem.

I added <generatePublisherEvidence enabled="false"/>  to the runtime section in the configs

<runtime>     
     <generatePublisherEvidence enabled="false"/>  
</runtime>

And services started with log4net appenders configs.

I edited
C:\Program Files\Qlik\Sense\Proxy\Proxy.exe.config
as well as
C:\Program Files\Qlik\Sense\Scheduler\Scheduler.exe.config
for appenders
C:\ProgramData\Qlik\Sense\Proxy\LocalLogConfig.xml
and
C:\ProgramData\Qlik\Sense\Scheduler\LocalLogConfig.xml
