呼叫无法进行MFA身份验证 [英] MFA authentication with call not working

问题描述

我认为已经有两个星期的电话身份验证工作不一致了.当我发现问题(因为我主要使用Authenticator应用程序)时，我检查了其他方式-SMS，Authenticator应用程序-这些工作正常.昨天我接到了电话 一次或两次，但是#不被接受.后来，它完全停止了呼叫.来自MFA服务器的测试显示:多因素认证被拒绝:电话不可到达".尝试更改"MFA呼叫者ID号码"

I think it's already two weeks with calls authentication working inconsistently. When I noticed (as I mostly use Authenticator app) problems, I checked other ways - SMS, Authenticator app - these were (and are) working just fine. Yesterday I received a call once or twice, but # was not accepted. Later on it stopped calling at all. Test from MFA server shows: "Multi-Factor Authentication denied: Phone Unreachable". Tried to change "MFA caller ID number" but it didn't help.

推荐答案

There are several reasons why you may try to sign in, but not receive the text or phone call. If you've successfully received texts or phone calls to your phone in the past and like you mention that the Text/Authenticator App are working fine, then this is probably an issue with the phone provider, not your account.
