Hi, we have a very rare problem with aws clientvpn, we have 62 routes/authorizations and the service works fine, we have windows clients with clientvpn software and linux clients with openvpn software.
But, when we add the route number 63, windows clients go fine, but linux clients (all of them) fails with messages like this:
...
