Hi Anaisdg,
Thanks for the quick follow up. Its much appreciared. I spent more time looking into it.
I was able to resolve the isssue. Fix was to use Openssl to convert the private key which had a pass phrase into a private key which doesnt use a pass phrase.
Seems like InfluxDB didnt like the ssl private key having a passphrase.
Will test comms today to ensure our data injestion is working again.
