Hello,
On our Vigor2926 after updating the firmware to the 3.9.9.8 version we cannot access the settings of any user in the "Vpn and Remote Access - > Remote Dial-In" user section.
When we click on the number of the user in order to access the settings we get the error : Authorization Error ! Browser not authentication-capable or authentication failed.

This happens almost all the time and rarely sometimes we might get into the details of a user, however it seems like a bug since we haven't changed anything after the upgrade of the firmware and previously everything worked perfect.

Could you please provide us any ideas in order to fix it?
Should we try to downgrade our firmware?
