requests.exceptions.ConnectionError

[lakka820]

Hi， I have used the image-ready2go, but when running the example, there will always be a requests.exceptions.ConnectionError error. I have investigated DNS, firewall, and network issues, but the problem remains unresolved. docker pull etenal/syzscope:ready2go docker run -it -d --name syzscope -p 2222:22 --privileged etenal/syzscope:ready2go docker attach syzscope cd /root/SyzScope git pull

What is the return of running this command curl https://syzkaller.appspot.com/bug\?id\=f99edaeec58ad40380ed5813d89e205861be2896

Dont need to paste the whole content if it's too long

The return is :curl: (7) Failed to connect to syzkaller.appspot.com port 443: Connection refused. But when I run the command out of the docker, the return is correct.
Image-ready2go did not report an error when downloading. How to Test or solve it. Thanks very much.

It might be something wrong related to your docker environment. Try to google the solution for the docker network issue. If it's still not working, try manually setup SyzScope on the host machine. The tutorial is on the README
