Pastehunter service random connection error

[sgbloke]

Hi,

The pastehunter.py is giving me random connection issues. Details as follows:
When running fine, there are 7 tasks when I do "systemctl status pastehunter.service"

Main PID: 89222 (python3)
Tasks: 7 (limit: 4633)
CGroup: /system.slice/pastehunter.service
├─89222 /usr/bin/python3 /opt/pastehunter/pastehunter.py
├─89259 /usr/bin/python3 /opt/pastehunter/pastehunter.py
├─89260 /usr/bin/python3 /opt/pastehunter/pastehunter.py
├─89261 /usr/bin/python3 /opt/pastehunter/pastehunter.py
├─89262 /usr/bin/python3 /opt/pastehunter/pastehunter.py
└─89263 /usr/bin/python3 /opt/pastehunter/pastehunter.pyMain PID: 89222 (python3)

When error occurs, the task becomes 2.

Tasks: 2 (limit: 4633)

CGroup: /system.slice/pastehunter.service
└─2390 /usr/bin/python3 /opt/pastehunter/pastehunter.py

Following are errors from "systemctl status pastehunter.service"

Apr 21 21:43:32 pbsvr python3[80377]: raise ConnectionError(e, request=request)

I have to do a systemctl retsart pastehunter.service to restart the service.
Please help to suggest how to prevent the connection error.

Thank you.
