I am trying to make a webapi call from apex class. I have an external data source based on oData for Lightning connect. And I am trying to qeury the external object records.
I am getting error - "common.apex.runtime.impl.ApexExecutionException: data.api.DataSourceException: The external system is unreachable. Make sure that the URL is correct in the external data source settings, and that the server's SSL certificate is valid for its domain name. Attempted to reach this URL....
Not sure why this is happening. Is there any issue from Salesforce end due to which the service is interrupted.
Anyone faced similar issue, Any ideas on the same.
