After upgrading to the ServiceNow New York release, access to external datastores will be blocked by due to increased security settings applied by ServiceNow.

ISSUE: Connection to the Evanios Datastore will fail.  Monitored Objects will not retrieve metric graphs.


In the evanios logs, you may see an error such as:

  • Error{communication} unable to perform ssl handshake: sslv3 alert certificate unknown

In the ServiceNow REST logs, you may see an error such as:

  • Response: [ERROR CODE: -1 ] No issuer certificate found for <datastore URL>
  • org.apache.commons.httpclient.HttpException: No issuer certificate found for <datastore URL> 

CAUSE: This issue is caused by tighter certificate standards in the ServiceNow New York release.

RESOLUTION: To remove the tighter certificate standards and revert ServiceNow functionality back to previous versions: 

  1. In the filter navigator, navigate to sys_properties.LIST
  2. Click the 'New' button to add a new property
  3. Fill out the record with the below details:
    Name = com.glide.communications.httpclient.verify_revoked_certificate 
    Type = true|false 
    Value = false
  4. Click 'Submit'
