App crashes because of OkHttp error

When I launch the app on my phone it opens and immediately crashes. Console says:

I just solved it. Seems like I put SimpleDateFormat("h:mn a"); while creating a new SimpleDateFormat object and apparently the "n" from the minutes must be removed; so it has to look like SimpleDateFormat("h:m a");
