TMS 2.8.3 and Delphi 12.3 with patch.

I've just updated the Delphi IDE to the last version (12.3) and at the same time the TMS Web Core components to the last version (2.8.3)

My frontend compiles well without problems, but when I execute the app, a quick command-line window opens and closes.

I put a breakpoint in the first line of the .dpr project, and the execution does not arrive at this point. It is closed before.

Can anyone help me? I don't know which way to continue solving this problem.

Thanks.

Now the problem was changed.

When I execute the program I get the next error:

If I close this error, the IDE becomes unstable. Nothing works. Each action show the next error:

I can't close the IDE. And I need to close it with the Task Manager.

Any one has had this problem and know how to solve it?????

thanks!

Solved. The first error. The last windows update was activated the firewall at the backend.

But what I can't understand is why this first error create the situation for the sencond error that the IDE was unable to solve?

I'm sorry but I do not know what could have caused this.
I think it is a good practice that when installing IDE & product updates to restart the IDE.

The second error is consecuence of the first one. In the time dedicated to go out of this situation, I was restarted the IDE and even the VM many times.

Finally this is not the problem.
I have the same problem. "Connection Refused" and what is more grave, after this error the IDE becomes unstable and I can't close it. An error of TMSWebCorePackage... avoid the use or the closing of the IDE.

I'm investigating.

The problem is not in the Backend. With the backend stopped, the problem is the same.
TMSWebServer maintains the server after the error, and the debug session in Delphi can be stopped due to an AVE.

I'm going to reinstall TMS Web Core. In this case, the Beta Version.

The problem persists, and I'm not working all day.

In a desesperate try I started Delphi in Administrator mode.

The problem continue!!!!!

With what exact steps can we reproduce what exact problem?

I don't know. I don't have this information. I believe the problem lies in TMSWebServer.

The last thing I tried was to execute the compiled program without the IDE, and I got an Empty blank page.

The next is one of the answers of GPT:

:white_check_mark: 5. Update TMS Web Core if the issue persists
Version 2.7.2 still had intermittent issues with TMSWebServer.exe on Windows 11, which were resolved in TMS Web Core 2.8.0 and later. If none of the above solves the problem, consider the following:

  • Completely uninstall TMS Web Core (and delete any leftover BPL, DCP files).
  • Install the latest version using TMS Smart Setup.

I don't know what is "TMS Smart Setup", but I've installed the 2.8.0 in a clean manner.

Now, I'm going to try a new clean machine. I need some time to install again Delphi and TMS Web Core.
