If you are asking about a problem you are experiencing, please use the following template, as it will help us help you. If you have a different problem, please delete all of this text 🙂

TIP 1: select at least one tag that further categorizes your topic. For example `server` for APM Server related questions, `java` for questions regarding the Elastic APM Java agent, or `ui` for questions about the APM App within Kibana.

TIP 2: Check out the [troubleshooting guide](https://www.elastic.co/guide/en/apm/get-started/current/troubleshooting.html) first. Not only will it help you to resolve common problems faster but it also explains in more detail which information we need before we can properly help you.

**Kibana version** :

**Elasticsearch version** : 8.6.0

**APM Server version** :

**APM Agent language and version** : 8.6.0 C#

**Browser version** :

**Original install method (e.g. download page, yum, deb, from source, etc.) and version**:

**Is there anything special in your setup?** For example, are you using the Logstash or Kafka outputs? Are you using a load balancer in front of the APM Servers?

Nothing special

**Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)**:

I'm trying to install APM Agent on my local to connect with my company dev elastic environment.  
I did it successfully with 2 personal elastic trial accounts. Just following the quick start with cloud.

But with my company elastic-kibana dev environment I got the following error when installing the APM agent from windows console:

```auto
