Trying to send logs to Splunk server using forwarder installed on Amazon Linux instances. I am not seeing any data on Splunk server. On forwarder side, I am seeing interfaces.sh related error in /var/log/splunkd.log.

I'm experiencing this issue with all amazon Linux servers.
Hi,
If data is being terminated before it even reaches the parsing queue indicates a connection problem as data is being dropped before it enters the first pipeline. Please check your firewalls, ports, IP TABLES etc to root out connectivity issues between the indexers and UFs/HFs.
It also worth checking the security groups of the Indexers and the UFs if they are the same or have similar permissions/rules.
Hope this helps.
I don't think it's a port issue. as it's able to connect to indexer on 9997 port as per logs. I also verified with telnet.
