Solarwinds AppInsight: Unable to create wsMan listener (Error code: 16024).

I was trying to get AppInsight IIS working on my SharePoint boxes. The automatic configuration option through SAM threw up this error:

Unable to create wsMan listener (Error code: 16024).

Upon checking the SPN on the SharePoint server I found that the http option were missing:

setspn -L Sharepoint01
Registered ServicePrincipalNames for CN=Sharepoint01,OU=Sharepoint 2010,OU=Serv
ers,DC=domain,DC=com:
CmRcService/Sharepoint01
CmRcService/Sharepoint01.domain.com
SMTPSVC/Sharepoint01
SMTPSVC/Sharepoint01.domain.com
WSMAN/Sharepoint01
WSMAN/Sharepoint01.domain.com
tapinego/Sharepoint01
tapinego/Sharepoint01.domain.com
TERMSRV/Sharepoint01
TERMSRV/Sharepoint01.domain.com
RestrictedKrbHost/Sharepoint01
HOST/Sharepoint01
RestrictedKrbHost/Sharepoint01.domain.com
HOST/Sharepoint01.domain.com

To fix this, you can add the spn by running the following command(s):

———-

Commands:

setspn -A HTTP/Sharepoint01 Sharepoint01

Output:
Registering ServicePrincipalNames for CN=Sharepoint01,OU=Sharepoint 2010,OU=Ser
vers,DC=domain,DC=com
HTTP/Sharepoint01
Updated object

setspn -A HTTP/Sharepoint01.domain.com Sharepoint01

Output:
Registering ServicePrincipalNames for CN=Sharepoint01,OU=Sharepoint 2010,OU=Ser
vers,DC=domain,DC=com
HTTP/Sharepoint01.domain.com
Updated object

Once this is done, go back to Solarwinds SAM and re-run the automatic configuration

If you host https, you will need to run the same commands replacing http with https.
