This file: /home/aashish/wellcore_fit/wellcore_fit/acms/main/dynamic_service_plane/config/initializers/init.rb wants to connect to the web to get some URLs but cannot for some reason. It's the getAllUrlsForDynamicPlane method in your cache_manager.rb file.

Comment out whatever is doing the web connection on init, and you should be able to proceed.
