I installed the EXT-Bring manually when I had this problem. I could sign in on the Android App. I could sign in on the Bring web page on Chrome. I could not make get the EXT-Bring to sign in with the proper credentials. I removed everything for EXT-Bring from my config.js file. I logged in to Gateway and installed EXT-Bring and now everything works. I cannot see ANY difference in the config.js file from my manual install and the Gateway install.
