firebird

问题 I have a problem connecting to Firebird 3 running on a Windows Server 2012 from a Windows 10 client. Firebird is running on the server and my application is ok and accesses the Firebird database on the server. However it cannot connect to the backup service. I installed Flamerobin on the client and it cannot connect to the server at all with an "unable to complete network request to host SERVER" error when I run "retrieve server version". So my application can run using the Firebird database
