@admin ,
Also I could see below exception in logs on another ws script:

Hi @rajanprabu ,

What is the time stamp you faced this issue: I think I faced the same issue today.

HB Stopped after : 2021-03-23 11:51:29.992341 (11:52 Heart beat never arrived)
tick stopped at : 2021-03-23 11:56:18.1555
Script ended at : 2021-03-23 12:09:29

This needed to fixed as SL/PB depends upon the ticks and we cannot afford ticks breaking for 10 minutes.

BR,
Ashok

Hi @rajanprabu said in HeartBeats Failed and reconnection:

It works fine when there is no network blips. I have requested reconnect module in python SDK exactly for this purpose. I faced this issue again today.
we will take your point into consideration on priority and revert you back.

@admin I'm also facing the same issue. I'm getting ticks but the log file has thousands of same reconnect messages.
