unigui app does not work with multiple logins

[AntonioCuomo]

when another user connects to the treemenu APP, it blocks and a connection error is reported. if the first user closes the browser, the 2nd app will work again.
in the log I have messages like this:

the app has always worked. I rewrote the form that gave an error but nothing has changed.
It is as if unigui does not allow multiple logins.
Unfortunately the app is active for customers

I've been trying to find the problem for a week.
I apologize for my English and for other messages already posted.

P.S.: other app run

Hello,

This problem is not related to Unigui. I have never seen this !

Try to review your code.

Also look at your DB implementation if any

My database is SQLServer and use firedac.

FDConnection  in unimainmodule. when closed connection last connection run.

if j run query sql from ssms the query is very slow o locked.

I guess a shell project reproducing this problem would help.
