Odd envelope routines parameter error Version 11.9 and 11.10

[MasterJames]

I just started getting this odd error when connecting a socket. The response crashes the nodejs 11.10 server
also other versions that worked for me otherwise too 11.9.
uncaughtException: [Error: 140631888258880:error:060CC07A:digital envelope routines:EVP_CIPHER_asn1_to_param:cipher parameter error:../deps/openssl/openssl/crypto/evp/evp_lib.c:81:

I recently rebuilt my certificate chain etc. Servers are topped up with highest bit Elliptical Keys
Signature Algorithm: sha512ECDSA Public Key: ECC (384 bits) Params: ECDSA_P384 Version: V3

Anyway same settings I used before. Tried both TLS 1.3 chrome://flags enabled and not, etc.
Problem exists for both Chrome Version 72.0.3626.109 (Official Build) (64-bit) and latest Firefox as well.
so it's seems a problem in websocket.
I've used OpenSSL 1.1.0g 2 Nov 2017 to create the keys.

Something is changed to trigger this error but I'm not sure what.
[Later I noted it's okay in NodeJS 10.8 and below]
Is there a way to better follow up and figure out what parameter is wrong and causing the error?

This does not happen with 11.8.0 and below. Something is failing since 11.9.0 and remains broken in 11.10.0
