Problems with forge tunnel

[Vanisha]

Hello everyone, 

I am very new to Atlassian Forge and am currently trying to develop an app using Forge.

For the installation, I have followed the instructions on this page: https://developer.atlassian.com/platform/forge/getting-started/

I am able to deploy and install the app on my local instance but unfortunately I am running into the following error when using forge tunnel.

Checking Docker image... 100%
Your Docker image is up to date.
docker: Error response from daemon: invalid IP address in add-host: "host-gateway".
See 'docker run --help'.

Forge tunnel initially worked but all of a sudden it stopped working (without me changing anything).

What I've tried already:

• Uninstalling and reinstalling forge/npm/node
• Starting/restarting docker
• Deleting the forge tunnel image and re-downloading it again. 
• Upgrading forge tunnel

Versions used:

• Node: 12.22.1
• Ubuntu: 18.04.2 
• npm: 7.16.0
• Docker: 20.10.2
• Forge: 1.4.0

Thanks in advance!

Hi

Actually, I think, it is a problem with the docker.

Anyway, remove && install every time solve this issue for me...

Sometimes it needs to install twice  (remove && install && install) :)

I don't know why but it works )

sudo apt-get remove docker-ce docker-ce-cli containerd.io
sudo apt-get install docker-ce docker-ce-cli containerd.io
sudo apt-get install docker-ce docker-ce-cli containerd.io

Docker 20.10.7
Ubuntu 20.04.2 LTS

Thanks Yuri for this hack with the double install. It didn't work in my setup after the first install, but then ... Feels a little bit scary though ...

I have:

Docker 20.10.8
Ubuntu 21.04 hirsute

I had problem with tunnel unable to connect when running forge on Zorin Linux in virtual machine. I had two network cards present - one nat to internet, one host-only.

I had to remove all network cards and leave only one card in the system. Since then forge works fine.

Hi,

do you have found an answer? I am facing the same issue.

I am using forge/docker inside a linux vm on a windows host.

Thx

Hello @Gernot Grames

unfortunately I have not been able to fix the problem yet. 

I also wrote a post on the Atlassian Developer Community and got some hints:

Maybe that could help you :)
