2.2 : Bug : "Unknown error" when stop GNS3

[Raizo62]

Hi

With GNS3 2.2, with an empty default config

I start GNS3, use the default project. I do nothing.

I close GNS3, then the console shows the messages "Unknown error"

2018-09-01 07:54:45 ERROR controller.py:416 The remote host closed the connection
2018-09-01 07:54:45 ERROR project.py:624 Unknown error

Even, i can't put any device on the topology (vpcs device for example)

Please start the server separately in a terminal using gns3server --local and let me know if you see any error after starting the GUI.

Thanks!

No error message : GNS3-gui close correctly. But i can't start again a topology with the same name : "Project "untitled" is opened. it cannot be overwritten" Again, i can't add vpcs device on the topology.

I couldn't reproduce the problem. Make sure all requirements have been installed using sudo pip3 install -r requirements.txt

[Raizo62]

It did already do.

I have tried with default config : same result.

I will send you an iso to test on it.

The shared iso is send

[Raizo62]

And I can't add device to topology : no error but the device is not on the topolgy

[grossmj]

I had a quick look and it seems the issue is with websocket connection with the GNS3 server. Have you tried to see if upgrading Qt to a more recent version would fix that issue?

[Raizo62]

I don't know : i use packages of stretch (last stable debian) with backport. I can test (and you can also because you have the iso ;-) [ don't forget to do "sudo apt update" before] ) But the others users who uses also stretch debian will have also the bug ?

I have fixed this in my last commit. Please give it a try.

[Raizo62]

Yes, it works :-) Thanks a lot :-D And i believe that the bug #2565 can be closed also
