Error: read ECONNRESET

Connection reset looks like a networking issue to me but I checked our firewall logs and I don't see any denies on packets sent by our Splunk HF where the add-on is installed.

Can you give me any guidance on how to troubleshoot this?

I did. It was a firewall issue after all. I didn't see it in the firewall logs initially but after I talked to our networking team, they found some blocked packets going to the Key Vault. After we allowed those, we saw more traffic being blocked, now going to the Event Hub itself.

Basically, we had to add the following to the Firewall whitelist:

Dest: yourKeyVaultName.vault.azure.net
Service: TCP/443

Dest: yourEventhubName.servicebus.windows.net
Service: TCP/5671

Awesome. Looking at our traffic, we've got the same issue. Thank you for your answer. This should solve our problems as well.
