Attempting to open Wireshark PCAP close project

[dtstanford]

I'm running gns3-server + gns3-web-ui on a newly installed Ubuntu 24.04 Server VM. I've installed the gns3-webclient-pack on my Macbook Pro (M1). Server packages installed are direct from GNS3 PPA, and WebClient pack is the latest release.

Problem: I am able to start a packet capture on a link without issue, however whenever I attempt to "start the capture visualization program" (when starting the packet capture) or "start wireshark" (once the packet capture has been started), all my node instances immediately stop.

I am seeing this when enabling logging:

If I browse to the gns3+pcap URL directly in Firefox, it successfully opens Wireshark without shutting down the instances.

i.e., taking this URL from my local Macbook (via ~/.config/GNS3/WebClient/launcher.log) works fine:

gns3+pcap://192.168.1.200:3080?protocol=http&project_id=78ab4342-3b11-4065-9e18-69b7072f0697&link_id=cbef0398-1369-4e96-a13e-7d8cb4ed9276&project=802.1Q&name=CiscoIOSvL2-2_Gi00_to_CiscoIOSvL2-3_Gi00

Thanks for your report. I have found this issue and fixed it. A new version should be released soon, in the meantime you can use Chrome instead of Firefox.
