Task for provisioning of WAP subscription fails with the error:
An unexpected exception occurred while calling the notification subscriber
The following errors may be found in Event Viewer on the server when WAP Admin API is deployed:
Error: HttpStatusCode: InternalServerError, ErrorCode: ErrorFromUnderlyingNotificationSubscribers, ClientErrorMessage:One or more errors occurred while contacting the underlying notification subscribers. The operation may be partially completed. Publishing notification to an end point failed with the exception: System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.

Issues with certificate or incorrect
Such errors could occur due to multiple reasons. First of all, please login to WAP node via RDP and open the endpoint link in browser on this node (by default it is
https://wap-aps:4486/wap/metadata.xml). The following cases can occur:
Certificate is shown with warnings. Then most likely it was incorrectly generated during deployment. Please repeat steps from WAP Deployment Guide (Section 3 Configure Windows Azure Pack, steps 10-26).
There are no certificate warnings, but some errors are shown in browser (403, 404, 500). Then it is necessary to check that POA management node (wap-aps) receives requests from WAP node. On MN node tail
https://wap-aps:4486/wap/metadata.xmlon WAP node.
If there is an error like "java.security.UnrecoverableKeyException: Cannot recover key" in
wap.logcheck that it is possible to list certificates using the password from
# /usr/java/default/bin/keytool -list -keystore /usr/local/share/WAP/WAPKeyStore -storepass <passwrod from wap-config.xml>
If there is nothing in wap.log, check that wap-aps resolves to POA MN node from WAP node
If there is "You are not authorized to perform this operation" in
wap.log, it could mean that the incorrect password was specified during deployment when executing the command:
PS> Set-MgmtSvcNotificationSubscriber -Name Billing -SubscriberType BillingService -Enabled $true -Endpoint https://WAP-APS:4486/wap/billing/ -AuthenticationMode Basic -AuthenticationPassword '<wap_billing_pass>' -AuthenticationUsername 'wap' -force
To fix it, execute the command with the correct password (can be found in
wap-config.xml) and restart IIS on WAP node.
- If above-mentioned steps do not help, compare wap-config.xml with wap-config.xml.template to be sure that it has proper format (i.e. it contains all the sections that .template file has).
Important Do not forget to restart WAP service on POA MN each time you are modifying WAPKeyStore or
