Having to restart heavy forwarder to get data from F5 network devices through control API

[mamulani11]

I have configured f5 network devices to a Heavy Forwarder. The data gets ingested for some time and then again it stops getting indexed. Every time I have to restart Splunk services on HF to start the indexing for F5 devices.
I got below error through internal logs on HF :

2019-06-19 14:53:17,812 ERROR pid=97727 tid=Thread-4677 file=F5_iControl_API.py:run:92 | Exception (it may be caused by unreachable F5 server "ip address" or wrong iControl API "Management.Folder.get_traffic_group" in configured template): Server raised fault: 'Exception caught in Management::urn:iControl:Management/Folder::get_traffic_group()

There are many errors like this.
Can someone please help me?

What Splunk Version and App are you using?

[mamulani11]

Splunk HF is 7.0.1 , For app I don't know how to check but if I check in apps.conf it is: 2.6.0(for f5 app)

This exception indicates a connectivity issue to your F5

Is it a fault from Splunk side or something with F5 devices itself? What can be done in such situations? How to resolve this issue?
