Auth via MLH occasionally fails on first few tries #33

If the time between browser sessions is long enough, the user gets logged out automatically. However, logging in afterwards via MyMLH fails the first try, but clicking sign in the second time works.

I've seen this happen a lot more often over the past month, to the point where I had to just stop and wait a few minutes before trying again.

Log:

app[web.1]: I, INFO -- omniauth: (mlh) Callback phase initiated.
app[web.1]: E, ERROR -- omniauth: (mlh) Authentication failure! csrf_detected: OmniAuth::Strategies::OAuth2::CallbackError, csrf_detected | CSRF detected

Unable to reproduce.
