Good morning,

I'm using the trial version and i would like connect my .net application to APM. I followed the steps that appears in the documentation but is not running.

I didn't change anything about the configuration of the APM or the indices, and I suppose my config file is correct (the serverUrl and token obviously is different):

```auto
> "ElasticApm": {
> "ServerUrls": "http://aaaaaaaa.westeurope.azure.elastic-cloud.com:8200",
> "TransactionSampleRate": 1.0,
> "SecretToken": "xxxxxx",
> "ServiceName": "Orchestrator_Invoicing_Development"
> }

```

I know that the default port of APM is 8200, but in cloud is the same? Is correct?

When I run the application I have this error:

```auto
fail: Elastic.Apm[0]
      {CentralConfigFetcher} Exception was thrown while fetching configuration from APM Server and parsing it. ETag: `<null>'.

Thanks for the help.

Hi @Kirtash,

> I know that the default port of APM is 8200, but in cloud is the same? Is correct?

On cloud it's the default https port, so in that case it is not 8220. Basically no port needs to be specified in case the server runs on cloud.

There is a button for this - you can click that and past the url - with that it should work:

The other thing I noticed you use `http` instead of `https` - that should be `https`, like this (with adapting the beginning similarly as you pasted):

```auto
"ServerUrls": "https://aaaaaaaa.westeurope.azure.elastic-cloud.com",

```

_so added `https` and removed the port._
