SplunkHttpEventCollector is not able to use SSL cert , error in azure app service

[gorarohit]

I have Azure App Service hosting Asp Net Core API ( . Net Core 3.1 ).

my Splunk target

<target name="Splunk"
				xsi:type="SplunkHttpEventCollector"
				serverUrl="https://<splunkserver>:8088/services/collector/event"
				token="token"
				source="${logger}"
				sourceType="_json"
				index="index"
				retriesOnError="3"
				batchSizeBytes="0"
				batchSizeCount="0"			
				maxConnectionsPerServer="10"
				ignoreSslErrors="false">
			<layout xsi:type="JsonLayout">
				<attribute name="date" layout="${date:format=MM-dd-yyyy hh\:mm\:ss.fff tt}" />
				<attribute name="host" layout="${hostname}" />
				<attribute name="logger" layout="${logger}" />
				<attribute name="message" layout="${message} ${exception}" />
			</layout>			
</target> 

Error

SplunkHttpEventCollector(Name=Splunk_wrapped): Failed to send LogEvents Exception: Splunk.Logging.HttpEventCollectorException: Failed to send request: InternalServerError
 ---> System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.
 ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.

I have uploaded valid SSL certificate in azure app service store and verified cert is available using code.

Note: I don't want to ignore ssl errors using ignoreSslErrors = true
I also verified ssl cert validation using curl.

Is this a valid purchased SSL cert or a self signed?

That error message is usually an indicator of self-signed certs, which is exactly what the ignoreSslErrors option is for.

This is a purchased valid CA cert and we verified this using CURL. This is a Entripsie level signed certs.
