ruby - Rails app returning 401 Unauthorized while logging in only in production -

-

i can't login in app deployed on heroku, 1 in production. on local machine 1 runs development work without problem. both databases same dump copies of each other.

i verified user exist in remote database , password given in correctly, both local , remote version same branch , synced.

i've tried this solution, config/initializers/session_store.rb looks this:

# sure restart server when modify file. filteredweb::application.config.session_store :cookie_store, key: '_filtered-web_session', domain: :all

someone suggested changing encryption key in config/initializers/devise.rb don't see , neither understand logic behind it.

versions

devise (2.2.3) rails (3.2.13)

i had same exact error... removing domain: :all fixed me. see a similar issue on github

as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
