I e-mailed support and got this answer:
"Your server must support the Transport Layer Security (TLS) 1.2 protocol and one of the cipher suites listed below:
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
TLS_DHE_RSA_WITH_AES_128_GCM_SHA256
TLS_DHE_RSA_WITH_AES_128_CBC_SHA256
TLS_RSA_WITH_AES_128_GCM_SHA256
TLS_RSA_WITH_AES_128_CBC_SHA256
Please make sure your server meets these requirements and then place the file in a path starting with “https://“"
What I did was get an SSL Certificate from LetsEncrypt, then on my Digital Ocean server, set up the SSL Cipher to only be set to "TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256" and it then verified. Hope this helps anyone with this problem, this information should really be documented.
