This error appears to our customers who used Forticlient to connect VPN.

based on each customer I upgrade and downgrade the clients in  customers PC based on the situation of each customer , the issue solved temporary but it repeating again from time to time and i am repeating the same steps to solve the issue.

kindly advice me if there is any permanent solution.

 on the other hand, another issue appears like the "Client connecting and disconnecting". I solved by remove the current client and install new ,and restart the PC, then it solved, but all this solutions are temporary and I am searching for better solutions.

kindly advice

thanks

    For me it was a TLS version mismatch on Fortigate and IE settings.

    Did it work previously before? If so, what changed?

     

    What version of FortiOS is the Gate running and what version of FortiClient is the endpoint running?

    At least two of our SSL VPN users got the exact error message with their FortiClient(VPN only). I won't say  the only one cause would show the error, but those two cases seemed to be related to Windows Updates. I told them to reboot their PCs at least a couple of times for WinUpdates to complete clean-up. One of them claimed he needed to boot four times. But after that they worked fine.

    yes it was working fine , the issue appears from last 3 weeks, and even  i tried various below procedures , they were only temporary solution , it will work but the issue will repeat after one to two weeks .

    -rebooting ,upgrading the client and downgraded depends on each case of customer.

    - i tried to install WAN mini port repair tool and do restart , then again install mini port installer tool and restart .

    - instead of client i ask the user to use browser but the same issue appears from time to time and I just solved it , by disable "Enable Enhanced Protected"

    I tried all above solutions and the issue solved temporary and repeated again .

    I am searching for the best solution which is stable for windows 7 /8 /10.

    current ios version 5.2
