issue

Unable to create project.
When I try to create a project from gns3 file, I get the following error.

Jul 16 02:54:42 cn-ab0914 gns3server[1592]: 2024-07-16 02:54:42 ERROR project_handler.py:210 Cannot load '/home/ubuntu/GNS3/projects/3rd-DynamicRouting-Intro1/3rd-DynamicRouting-Intro1.gns3' because the server has not been started with the '--local' parameter

When I try to create blank project, I get the following error.

Jul 16 05:26:07 cn-ab0914 gns3.desktop[4102]: 2024-07-16 05:26:07 CRITICAL topology.py:258 The path is not allowed

The gns3server process is follows.

ubuntu@cn-ab0914:~$ ps -ef | grep -i gns3
root        1592       1  0 02:47 ?        00:00:05 /usr/share/gns3/gns3-server/bin/python /usr/bin/gns3server

reproduction procedure

1. install gns3server from apt ppa(v2.2.48) on Ubuntu22.04. ( https://docs.gns3.com/docs/getting-started/installation/linux/ )
2. select <Yes> the following question. (if select <No> , this problem does not occur.)

Configuring gns3-server 

Use Systemd to automatically launch the GNS3 server at boot.
Do you want to enable and start the GNS3 server as a service?

3. start GNS3
4. try to create project from gns3 file or create blank project, the problem occures.

if select <No>, gns3server process is follows.

ubuntu@cn-ab0914:~$ ps -ef | grep [g]ns3
ubuntu      8788    2995 23 02:27 ?        00:00:01 /usr/share/gns3/gns3-gui/bin/python /usr/bin/gns3

[WhatsTheIP]

Found a work around on how to resolve the issue while preserving remote server connectivity & keeping my topology & nodes intact.

I'm adding this as a note for now for historical purposes, updating the bug link below with my work around if others face this issue:

• [Bug][GNS3 2.2.48] - Path Is Not Allowed gns3-gui#3604
• unable to create project when use systemd (PPA install 2.2.48) #2403

---

IMPORTANT:
#1) - Make sure you kill the gns3server 1st before you attempt to run gns3server --local from the CLI.
#2) - If you don't know how to do that, go down below you'll see where I identify if the gns3server service is running and how I killed it.
#3) - You don't need to run --debug but I did it to troubleshoot the issue to see if the server or client returned any logs.
