HealthCheck Assistance
The Health Check has detected that there is a resolution issue involving a configured endpoint.
A number of ENPS applications are hosted via Windows Internet Information Services (IIS) and have endpoints configured. The HealthCheck confirms that the endpoints are able to resolve the address. If they are not able to resolve, it may indicate a simply syntax error when typing the endpoing address, a DNS resolution issue or if using HTTPS, a certificate issue. If the later, check the certificate expiry and follow the resolution below to renew it.
The two entry endpoints are serviceAddress and BackupserviceAddress.
Open Computer Management and navigate to Services and Applications | Internet Information Services (IIS) Manager
Expand the server entry in the mid-pane and select Sites |Default Web Site, then select the application cited.
With the application highlighted, from the right pane, select Application Settings from within the ASP.NET section where the entries for the two keys above can be checked.
If the keys are entered correctly, attempt an ICMP ping request or tracert to ascertain how the resource is being resolved. Depending on the result, contact your corporate IT/network team to fix the endpoint resolution.
The commands to check the resolution are:
ping <endpoint address from serviceAddress or BackupServiceAddress> (do not include the HTTPS/HTTP or /NomWebServices3JSON text)
tracert <endpoint address from serviceAddress or BackupServiceAddress> (do not include the HTTPS/HTTP or /NomWebServices3JSON text)
Periodically this can be caused when the IIS | Application Pool associated with the application hangs or crashes. Using the endpoint in the notification, copy it to a web browser to see if the application responds. Should the error shown be an IIS:500 error, on the target server, Open Computer Management and navigate to Services and Applications | Internet Information Services (IIS) Manager. Expand the server entry in the mid-plane and select Application Pools, right click on the application pool associated with the failing application and select "Recycle". Retest via the browser method stated earlier.
On the target server, Open Computer Management and navigate to Services and Applications | Internet Information Services (IIS) Manager
Expand the server entry in the mid-pane and select Sites |Default Web Site | Bindings (right pane options)
Highlight the "https:443" entry, select Edit
In the SSL certificate drop down list, ensure the correct certificate is selected. Click "View" to see the details of the certificate to check that it has not expired.
If using HTTPS, ensure the certificates and DNS are correct configured.
If using self-signed certificates, ensure that on the remote systems, the self-signed certificate is imported into "Certificates - Local Computer | Trusted Root Certificate Authorities | Certificates"
