Any word on this?
On my Mudi, it still throws an error if I use TLS-Ciphers ‘ECDHE-RSA-CHACHA20-POLY1305’. The error says that the OpenSSL version is 1.0.2.

library versions: OpenSSL 1.0.2p 14 Aug 2018, LZO 2.10

NOTE: the current --script-security setting may allow this configuration to call user-defined scripts

OpenSSL: error:1410D0B9:lib(20):func(269):reason(185)

Failed to set restricted TLS cipher list: ECDHE-RSA-CHACHA20-POLY1305
