It may have stopped working either when we updated from 9.7p6 to 9.7p11 or when we disabled all ssl / tls versions other than TLS1.2.

Thanks in advance for any help.

Harvest 1.6 was not supported since we released Harvest 2.0 in May.

We highly recommend you move onto Harvest 2.0 https://github.com/NetApp/harvest/releases which is now a open source software supported by the open source community: https://github.com/NetApp/harvest/blob/main/SUPPORT.md

Thanks,
