@jll I cannot say for sure, but considering ES3300 is for more than 2 years and Firmware 7.4.5 for over 6 years out of support, I would assume that TLS could be an issue here. Are you sure you wanna have such an old system in production?
Did you tried the diagnostics on the ES and was it able to connect to your downstream?
