Hi,
I'm using R16B01.
I'm getting an error even when adding the Ciphers:
{{badmatch,{error,{options,{ciphers,[{ecdhe_rsa,aes_128_cbc,sha},{dhe_rsa,aes_128_cbc,sha},{rsa,aes_128_cbc,sha},{ecdhe_rsa,aes_256_cbc,sha},{dhe_rsa,aes_256_cbc,sha},{rsa,aes_256_cbc,sha},{ecdhe_psk,aes_128_cbc,sha},{dhe_psk,aes_128_cbc,sha},{ecdhe_psk,aes_256_cbc,sha},{dhe_psk,aes_256_cbc,sha}]}}}}
Port = 5070,
Ciphers = [{ecdhe_rsa, aes_128_cbc, sha},
{dhe_rsa, aes_128_cbc, sha},
{rsa, aes_128_cbc, sha},
{ecdhe_rsa, aes_256_cbc, sha},
{dhe_rsa, aes_256_cbc, sha},
{rsa, aes_256_cbc, sha},
{ecdhe_psk, aes_128_cbc, sha},
{dhe_psk, aes_128_cbc,sha},
{ecdhe_psk, aes_256_cbc, sha},
{dhe_psk, aes_256_cbc,sha}],
Options = [{versions, ['dtlsv1.2', dtlsv1]},
{cb_info, ssl_udp},
{reuseaddr, true},
{active, false},
{ciphers, Ciphers},
{certfile,Cert},
{keyfile, Key}],
{ok, LSocket} = ssl:listen(Port, Options)
