The client struggles to connect when downloaded for the second time

[JarrenGoes]

Hy, when I make some changes to my program (not in the mqtt part of the plc program) and download the project then the plc switches between is connected and not connected on random ocasions. After resetting the plc the problem is solved and the client stays connected.

Is this normal? can this be solved?

Does the same problem happen if the client is deliberately disconnected from the server, using the Disconnect method, before the new program is downloaded?

If the client simply stops communicating with the server (as might happen if the disconnect method is not called), then perhaps the server will not accept a new connection from the same client until after a timeout period.

If i disconnect before uploading it works the next time.
Is there a way to dissconnect when the plc is stopped so i don't need to disconnect manualy?
(maybe a variable that becomes TRUE when stopping the plc)

Hello,
I have exactly the same problem with this new version of IIOT Library.
Have you already found any solution for this problem ?

Hy,
In my project i integrated a button in the eHMI, that reboots the plc using the PLCNEXTBase library.

It would be nice if this problem is solved by changing something in the library.

I have passed this request to the developers of the IIoT Library.
