" Failed to read: session.screen0.*" on firefox debug node startup

[azakordonets]

Hi,

I was trying to setup selenium grid with fig and docker on Mac OS. But on a startup every node was complaining about same problems :

What this all complains mean and how could i connect to it through vnc? I tried all possible solutions, but it doesn't work for me.
In my bashrc file i have

export DOCKER_HOST=tcp://192.168.59.103:2376
export DOCKER_CERT_PATH=/Users/biercoff/.boot2docker/certs/boot2docker-vm
export DOCKER_TLS_VERIFY=1

and i tried to run

vncviewer 192.168.59.103:49155

but ended up with an error. I also tried to access to vnc of each node, but with no success :

docker inspect $(docker ps -q) | grep IPA
"IPAddress": "172.17.0.13",
        "IPAddress": "172.17.0.11",
        "IPAddress": "172.17.0.9",
        "IPAddress": "172.17.0.7",
vncviewer 172.17.0.11:49155

And as a result - an error. What am i'm doing wrong ?

Thanks in advance

I have the same issue with chrome debug also. Any help on this issue is really appreciated

[snowe2010]

any more information on this? I'm also seeing this problem. My nodes are actually crashing (because of the errors I think)

[elgalu]

Can you please try to recreate with this standalone version: https://github.com/elgalu/docker-selenium#non-privileged ? That would help to narrow the problem.
Also please check if this is the error "UnknownError: session deleted because of page crash from tab crashed" elgalu/docker-selenium#20

[diemol]

@azakordonets that is not really an error, is the normal output when the debug images are starting their VNC.
Yes, maybe it is annoying, but this is the normal behaviour.

@snowe2010 If the tests crash, please post the related errors to them.

@diemol I haven't touched selenium in 2 years now, so I won't be able to reproduce. Go ahead and close if you need to.
