CL+_sender_daemon Sending retries over Connection aborted

Issue

cl_plus_sender service periodically reports the following:

(CL+_sender_daemon) [ERROR] Sending retries over, still no success: ('Connection aborted.'...onse'))

(CL+_sender_daemon) [ERROR] es_sender error while requesting cm.cloudlinux.com: ('Connecti...nse'))Environment 

Environment

• CloudLinux Pro
• Centralized Monitoring

Solution

These messages mean that connection was refused between the server and cm.cloudlinux.com.
There is no impact associated with said messages, and they could be seen from time to time due to some temporary network issues. 

For example, if we run ping, we may lose a few packets, but it is not a critical issue.
