The only thing I can see of relevance in CGPro's History files is in 4.3c3: TLS: the Weak Ciphers option is implemented. Can you change your config to only offer "strong" ciphers? Main config setting "tls_require_ciphers" might see you right by limiting the available ciphers to something that works. Unfortunately you may need trial-and-error here - start with one and widen the set.
