openwebui cannot connect to pipeline

[flyfox666]

After reading the instructions and installing it, I found that I can never connect to pipeline.

env：window11, wsl2, dockers for desktop

This is the status of pipeline's docker.

Seems like your Open WebUI docker container can't reach Pipelines, I'd suggest you look into troubleshooting Docker networking issues.

[flyfox666]

I just tried reinstalling and restarting docker and rebooting my computer and then the problem was solved, thanks a lot!

[rootcli]

I had a similar problem. here is what I did:

I removed pipelines container from docker
I removed the pipeline root folder, in my case it was "/opt/pipelines"
Ran docker command again:
docker run -d -p 9099:9099 --add-host=host.docker.internal:host-gateway -v /opt/pipelines:/app/pipelines --name pipelines --restart always ghcr.io/open-webui/pipelines:main

And it worked for me, hope it helps

I had to use the local IP address assigned to the pipelines container, in my case it was : 172.17.0.4

[FlorianBoehler]

This also worked for me.
To get the IP, I used:
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_id

[David-Zeng]

Thanks. It worked for me as well
