I face an issue by using a REST connection. I tried to contact a WM REST service from another WM application.
When the Rest service simulate http 503 error, I can’t get the message associated with the errorcode.
With errorcode 500 or 502 (for example)I’m able to get the linked message.
Do you know I can get the error message for 503?
Normally HTTP-503 reason would be due to target server issue.
The HyperText Transfer Protocol (HTTP) 503 Service Unavailable server error response code indicates that the server is not ready to handle the request .
Please check it once with concerned app provider team
Reboot your server.
Check to see if your web server is going through maintenance.
