Client Authentication Agent not able to Login in Windows 8

Question

Dear all,

We have recently upgraded firmware version v19.01 in our XGS2300 High Availability setup. After that we couldn't able to login into Firewall through Client Authentication Agent in particularly windows 8 devices and there is no problem in windows10/11 devices. We tried by uninstalling the existing client and installed the new downloaded agent again from the from the firewall.But we can't able to login.

Anybody facing this problem ? kindly let me know the solution for the same?

so you moved from 18.5, if so that's possible as in v19 SFOS have removed the support for weak cipher suites - and that could lead windows7/8 clients can't talk to v19+ firmware. We recommend to move to windows 10/11.

I afraid there isn't alternate (other than moving clients to windows 10/11). Weak ciphers were removed to overcome security vulnerabilities.
