Password problem

I tried to download the data from API cloud. I realize that there is problem with my password. When I use app on my phone, I log in via facebook. However, when I log in with facebook account and password to flower power on the app, it did not work.

When I use R package to extract data, the error message came,

“Error in curl::curl_fetch_memory(url, handle = handle) :
SSL peer certificate or SSH remote key was not OK”

I tried to reset the password for the facebook account on the app, it showed reset link has sent, but never come.

I am wondering if log in via facebook, the password will be something else than original facebook password?
