Cause

Per ASM Engineering, all US stations fail with SSL read error receiving data from peer (curl error 104). This happens when the other end (the monitored service) just closes the connection. It again happens intermittently.  The issue should be directed to your service provider.

Environment

Release : 10.1

Component : CA APP SYNTHETIC MONITOR (WATCHMOUSE)
