Subject Cannot access database on second server.


My software using FB 2.54 (SuperServer) and Firedac (Delphi 10.1) connected fine on a workstation to the "SERVER".  All the required connection files are in the software folder and I did not do the FB Client installation on the workstation.

Another company then did a custom Firebird server (2.6 Classic) installation on the workstation which runs from a customize folder.  Since that installation I can not connect to my database on the original server.  It does not give any errors on connection, but eventually fails with a "connection lost".

I tried the FB 2.6 FBClient.DLL files, no joy.  Other workstations connects fine to both servers.

Any idea where the problem/conflict lies and how to resolve it?

Kind regards
