Dear Abed,

checking the F5 knowledgebase article, I would interpret the correct syntax as follows:

set ga_code [expr {0x[string range $token $offset [expr {$offset + 7}]] & 0x7FFFFFFF} % 1000000]

But I don't have tested it right now, so please give it a try.

Thank you!

Regards,

Stefan 🙂

    I actually tried this

    The F5 accept the irule

    and the error disappears

    but the APM connection is not working anymore

    when I try to connect , I pass the username / password , then I type the OTP , and when I click 'next' the APM resets the connection and start over from the beginning

    so it stop resuming to establishing the connection
