I am working in a existing project that has a socioboard setup. I have been assigned to solve the login/sign up issue. The project is remotely hosted. The issue when someone tries to sign up with google,facebook or other social medias it is displaying "some errors occurred, reload the page". sign in email is also giving a red image notification. In the console it giving the following errors.
