Failed to authenticate w/ Google Authenticator when configuring OpenVPN on OpenWRT
问题 I'm quite new to OpenWRT and I'm facing some problems here. I set up the OpenVPN server on a Ubuntu using OpenVPN Access Server web GUI, and correspondingly I got the client profile client.ovpn . Also I enabled "Google Authenticator Multi-Factor Authentication". When I configured as a client using client.ovpn , it worked perfectly on my phone, my other PC, but it just failed when I tried to start a client on OpenWRT on my router.
