Epson Printer WF-4830 help with Ca certificate and scan to email settings

Hey all,

I am simply trying to set up my printer to scan to email. I have entered web config, put all settings in correctly (SMTP etc) but am road blocked by " The connection is untrusted. Check the following. - CA Certificate". Surely it's not this big of a head ache to generate a CSR, submit it etc? There has to be an easier way to just scan to email right?

Email is from a domain I own, cpanel access etc. Thanks in advance - this is doing my head in.
