Why can not login and connect to this Sophos SSLVPN?
This is using Sophos UTM 9 firewall. However, recently found that the user can't logon as this user was repeatedly looping to the QR code and then back to the initial user login page.
This is how the whole thing look like,
a. user browse to the sophos utm9 login page - https://119.xxx.xxx.xx:4443;
type in the registered username and password
b. user will be directed to the QR code for 
otp, user has to use sophos authenticator to scan and then 6-digit code is shown
c. After click "proceed with login", straightaway user is being automatically re-direct back to the initial login page
On the same time, see there are 10+ online users. What's went wrong?
Thanks

same understanding-problem with some users .. sometimes:
After the user is being automatically re-direct back to the initial login page, the user has to use username and Password+Token to login.
Some users don't append the token at this step...

Don't really understand. What can be done here to troubleshoot and solve the problem?

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection. Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
