** (MatchError) no match of right hand side value: {:ok, :http}

[Teifion]

Discord have (possibly just this morning) changed something and the login breaks.

I have managed to work around it by changing line 103 in ratelimiter.ex to {:ok, _} = :gun.await_up(conn_pid) but this doesn't feel like a good solution long term. I'm creating the issue in part to help people searching for it.

This issue may be resolved on the master branch.
It's related to PR #522.

Oh even better, I didn't see an open issue with this error code so I thought I might be the first person to discover it. There go my hopes at achieving internet fame!

Got the same thing I think?

** (Mix) Could not start application nostrum: Nostrum.Application.start(:normal, []) returned an error: shutdown: failed to start child: Nostrum.Api.Ratelimiter
    ** (EXIT) an exception was raised:

@mcfiredrill Yes, this is exactly the error I had. Based on the above comment you can either point to master or like I did, put a bit of a hacky solution in.

[mcfiredrill]

Fixed in master for me thanks @Teifion

using master didn't help at all - only introduced new problems and issues.

[jchristgit]

Using master is the fix for the match errors above.

For the later error

** Reason for termination = error:{'function not exported',{pg,monitor,2}}

You need to upgrade to OTP 25.1 or above, where :pg.monitor was introduced. https://www.erlang.org/doc/man/pg#monitor-2

This bug is a breaking change to Nostrum and should be hotfixed or at least put in a new version 0.8.1. That is more reliable than to change one's dependency version back to {:nostrum, github: "Kraigie/nostrum"} or implementing a downgrade.
