What versions of Elixir, Erlang, and Ubuntu are you running?

bsnyder788 commented 7 years ago

@BlakeWilliams I am seeing the same exact errors after upgrading to elixir 1.4.5 and Erlang/OTP 20 [erts-9.0] on Ubuntu 14.04.

It was working fine on elixir 1.4.4 and Erlang/OTP 19.

I could work past the error by editing wsc_lib.erl line 171 and 227 and replacing crypto:rand_bytes with crypto:strong_rand_bytes on each line..but more errors follow after those changes

I guess it's time to upgrade https://github.com/jeremyong/websocket_client dependency. The issue was already fixed in this commit .

Just pushed 0.12.0 that has #138. Feel free to reopen if that doesn't fix it.
