SSL VPN portal login not working - username and password cannot be empty

SebastianS

Hi all,

I'm trying to set-up 2FA for SSL VPN users according to

https://www.sonicwall.com/support/knowledge-base/how-do-i-configure-2fa-for-ssl-vpn-with-totp/190829123329169.

When trying to log on to the SSL VPN Portal with a correct username and password to bind the 2FA authenticator app it always immediately shows the error "Username and password cannot be empty." after clicking the login button. Despite both was entered correct.

Details:

• Sonicwall TZ270 running SonicOS 7.1.2-7019
• SSL VPN running on customized port 4437
• SSL VPN portal ("Virtual Office") disabled for non-LAN interfaces and accessed from LAN
• SSL VPN activated for zones WAN and LAN
• SSL VPN access itself without 2FA is perfectly working
• Login tried with different most-current browsers: Chrome, Firefox

Any help is appreciated! Thx.

Kind regards,
Sebastian

Firmware 7.1.2 is known to be pretty buggy, try downgrading.

Note it is destructive.

Otherwise open a support ticket.

Thanks for your reply @TKWITS. As the device itself is running fine in all other regards, I would consider a destructive downgrade of the firmware as ultima ratio to solve that…hopefully...

Despite having active gateway service licenses on a registered device, I'm not able to open a support ticket as it simply tells me that the maintenance contract has ended. 🙄

Anyone else maybe facing the same issue?
