wordpress + whmcs bridge latest version error when login

anybody experiencing the same issue like below ?

i currently using cpanel latest version, wordpress latest version and whmcs bridge free latest version.

my whmcs is installed in https://billing.neorack.host

my wordpress + whmcs bridge link :
https://neorack.host/whmcs-bridge-2/
user : [email protected]
pass : test123

when login it will show error “Opps… that page can’t be found”
i believe it will be something like permalink issue ?
since the link redirect to something like below

https://neorack.host/billing.neorack.host/dologin.php

is there anyway to fix this issue
when login it should be login into the whmcs client area/customer dashboard.

any help would be appreciate it.
thank you
