Problem

this.$auth.loginWIth() works on pc(desktop) properly . but on mobile, it shows me NetworkError(without status code.)and also it doesn't send request. (I checked it by backend's log) but it shows me NetworkError.
i don't know why loginWith() don't work on mobile phone only. i tried to check this with other persons phone. but occurred same problem.
i already checked cors policy and firewall.
