unable to connect to pulbic clusters

I'm trying to retest an old piece of software with pai_module.dll version 3.0.61.0, used by a client with their own centera cluster

I enabled 3218 for tcp/udp on my router and firewall, and plugged in current public test test server info

but this is failing:

FPPool_Open(

"168.159.214.27,168.159.214.28,168.159.214.29,168.159.214.30?D:\path/emea3profile3_rdqew.pea"

);
