forwarder stopped sending to indexer but continues to send to 3rd party receiver

[Log_wrangler]

Any help on this is greatly appreciated.

I have a bunch of servers with UFs sending to a HF that is configured to send cooked data to splunk indexers and raw uncooked to a 3rd party receiver.

The flows have been running fine, but suddenly data to the indexers stopped.

I am looking for any suggestions to troubleshoot this.

Thank you

• should mention, that eventually everything stopped receiving, after a few minutes.

Thanks, did that and could see that the 3rd party receiving ip was blocking, so there must have been a build up that ultimately stopped the forwarder...
