GET /incidents/<incidentId>/notes and /incidents/<incidentId>/status_updates sometimes return response code 0

Hi, when I’m calling /notes and /status_updates most are successful but they sometimes fail and do not provide a useful error message. When it fails the response code is ā€˜0’ and the error message is ā€œread ECONNRESETā€.
I am calling these APIs about 60 times within a minute or two.

The same error occurs when I’m calling the APIs separately an hour apart. Most of the requests are successful but there’s a few calls that fails randomly with response code ā€˜0’.

What is causing these errors?
