"SSL: error:0A0000B9:SSL routines::no cipher match" with Mozilla modern ciphers v5.5

[petecooper]

I am following up with fresh eyes.The 3x ciphers that cause problems are:

TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256

I have just noticed each cipher name above has an underscore `_` character
as a separator. The working ciphers all use a dash `-` as a separator.

Might that be a factor in Nginx rejecting the cipher names?
