Fatal Authentication Error when i try 'Pod Install' command - ios

Question

I am trying to implement my framework library into my project using Cocoa Pods.
I found similar questions but their error messages were different from mine. Hence i am posting this question.
I successfully created pod file using pod init command and opened pod file in TextEditor and saved my code
The following is my Pod File Content
#platform :ios, '8.0'
source 'git#git.assembla.com:ioslibs.podspecs.git'
source 'https://github.com/CocoaPods/Specs.git'
target 'WatchList' do
pod 'matrix'
pod 'lego'
end
When i try pod install command at my Project's Directory, it is showing the following error.
Note
I gave Valid Username and Password.
But it gave me the same error even
if i give (Wantedly) incorrect Username and Password.
I hope there is no problem to do with the username and password, but i can't find what's the real problem is.
Thanks for the time.. (:
UPDATE
When i try pod install --verbose
GaneshBabu:WatchList ganeshbabu$ pod install --verbose

Answer 1

This is what my pod file looks like:
May be you can cross verify with this:
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, "8.0"
use_frameworks!
target 'WatchList' do
pod 'matrix'
pod 'lego'
end
Also you can cross verify the directory in which you are installing pods
