Requesting Access Token API failed 3 times

in Development
Hi
We have build an web service to extract daily sale data from the retail application. This web service is working fine for the last couple of weeks. Since 3 weeks we have scheduled the web service to run at 22:45 CET. The web service failed 3 times, because it was not able to get the Access Token.
When I re-run the web service again the next morning, it runs fine without any issues.
The web service is not able to find the external host: cloud.merchantos.com
The errors description in our web server is: oracle.fabric.common.FabricInvocationException: javax.ws.rs.ProcessingException: java.net.UnknownHostException: cloud.merchantos.com
Is this a known issue, or is this issue caused on our end?
Best regards Roel van Ree.

We had no issues for last days with the API server. How often does your integration run? Are you obtaining a new token through the refresh token endpoint?
