And then I disabled the auto-startup of WebServer-service and launch the WebServer-node manually, it shows following error:

Has anyone has the same problem? I would really appreciate it if anyone could offer some advice.

Thanks in advance

Hello,

This issue is due to the qre_g1 webserver not being properly cloned and/or the libwebserver.py not having execution privileges.

For the second one solution is to:

cd /opt/mybotshop/src/mybotshop/g1_webserver/g1_webserver
sudo chmod +x *

Hi, quick question, Where can I download the qre_g1 webserver? I re-flashed the Jetson Orin

Provided that you have access from here

https://github.com/MYBOTSHOP/qre_g1

If you do not have access, send your order number with your github username to support@mybotshop.de and they will give you access.

Thank you for the reply, I don’t have access yet but will email the support right now!

I have the same problem. It seems that the file “libwebserver” doesnt exist. Where can i get this file?

Hi，
It seems in old version of repo qre_q1 this lib file is missing. You can contact the support team (You can find the contact in the comment) and get the latest version of this repo. After re-Building/installing all packages the Webserver and RemoteDesktop will work as described.

Best regards
