FixHub Web Console Connection Error on Ubuntu(Solved: user permission)

I was encountering a "Connection error" when trying to connect my FixHub Smart Soldering Iron to the web console at ifixit.com/fixhub/console. I am running Ubuntu 24.04.2 LTS and using the latest Google Chrome browser.

The error message stated: "Make sure you do not already have another connection open and try again."

I tried the following troubleshooting steps without success:

  • Fresh boot with no other applications or browser tabs open.
  • Tried multiple USB ports.

The solution that worked for me was adding my user account to the dialout group. I used the command: sudo usermod -a -G dialout <username> (replacing <username> with my actual username). After running this command and then logging out and back in, I verified I was added to the group using groups <username> and was then able to connect to the web console successfully after a reboot.

This seems to be a common permission issue on Linux systems for accessing serial ports.

Ugh, Yes. Linux doesn't give permissions to access serial ports to users by default. We'll look into maybe detecting linux from the browser and suggesting this.

Thank you for reminding us!
