We have an application monitoring application called Nagios XI in our organization and recently we received an alert - ** PROBLEM Service Alert: <domain>/prod: user: auth: https_<domain> is UNKNOWN** with an ERROR: Unable to connect to host http://localhost:4444/wd/hub. Contact EPSM. Message: Could not initialize class sun.net.www.protocol.http.HttpURLConnection
The error message came at 12:19 PM on Monday and then at 12:57 got another alert notifying a RECOVERY.
RECOVERY: Closed session and quit window
In order to find the root cause of this issue, we have looked at the Event Logs and SharePoint Logs (Verbose) to find any reference for http://localhost:4444/wd/hub and class sun.net.www.protocol.http.HttpURLConnection but with no luck.
Ideas?

Thanks for reaching out.
wd is the short form of WebDriver
hub refers to Selenium Grid configuration where the two components are:
Selenium Grid Hub (is commonly termed as hub)
Selenium Grid Node (is commonly termed as node)
wd/hub is the part of the uri through which the node communicates with the hub
Hence to troubleshoot more I would suggest you to check Selenium Gird logs from application folder.

Where do you suggest to check the Selenium Grid logs from?
Do you mean from the application folder in the event viewer and filtering out the logs source as Selenium.
If so, we do not see "Selenium" listed in the application.

Found the answer for my own question from our application monitoring team.
"This is an older synthetic transaction and there are times that the check fails for an unknown reason. Normally, the error clears on the next check, but in this case it did not until Selenium services were restarted.
When you see Unable to connect to host http://localhost:4444/wd/hub, that is a Nagios/Selenium issue, not a service issue."
