Only thing I can think of is a virusscanner which holds the connection too long and a subsequent chevron is refused. What virisscanner (if any) are you using?

Did you try disabling or uninstalling it ?

That's make sense.

I am using Comodo Firewall 5.12.252301.

I remembered allow Comodo to let Lazarus made IP Connection.
After allowed, should be no restriction again.

I will check again for a few more days, caused this error happen randomly.

Right now , with Firewall ON, TSQLConnector runs OK. Will turn Firewall Off if error happen again and see the result.

After a few tests, I rarely faced the problem again.
And if it occurred again, restarted Lazarus solved the problem.

It was a mystery why the problem occurred, but since the solution found, I will close this thread as SOLVED.

Thanks to everyone that has helped me.

Hello folks,
I´m having this error message
-connection shutdown"

My Lazarus project (Lazarus 2.0.2) has a button to test the database (Firebird 2.5.6) connection, and the error ocurs in the SECOND click on that button...

It started with none changes in my software, but the computer has "windows 10"... (there is this june´s windows updates: KB4023057, KB4503286, KB4503308  :( )

And on Windows 7, the same exe file don´t show the error message...

The fbclient.dll is on the same project´s path.

I did a test, running the prior version of my project compiled in Lazarus 2.0.0 and ocurs the same error message.

Has anyone a solution? I found out, that this error appears if the last connection in a project is closed. It seams, that the driver is unloaded.
