Hi All,
Recently we faced one strange issue that is all of sudden SAS Web applications stopped working. when I check the sas.servers script all services are up and running. When I open the Web URLs getting the following error. "This page can't be displayed. Make sure the web address https:// XXXXX is correct ". We verified all SAS web services logs but didn't find the root cause. We restarted all SAS web service then it worked. But we need to know what is the root cause for this issue.
When we check the WebServer logs under the below path "/opt/sas/config/Lev1/Web/WebServer/logs/error.log" found the below error message.
