I installed "contacts" gem on my local machine, wrote some code to get yahoo, gmail and hotmail contacts, and it was running smoothly. I moved the code to a server for testing, my gmail and hotmail contacts were still running, but Yahoo gave me the following error:
Contacts::AuthenticationError: Username and password do not match
I am sure that email and password are correct. I tried my code on another server the behavior was the same ...
Any hints?
