Dashboard appears for split second then blank

I have been playing around with ray the past few days specially the rllib tutorial. I can’t seem to get the dashboard to work though and it’s really frustrating. No errors when I use ray.init() and it give me a ‘webui_url’: ‘127.0.0.1:8265’ so that seems good. I installed ray with pip install ray[default] as it was missing dependencies for the dashboard originally.

Python - 3.8
Ray - 1.9.1
aiohttp - 3.8.1 (Someone said this maybe an issue in another post? I tried to downgrade with no luck)

Would really appreciate any help! Thanks.

getting the same issue with ray 1.9.1

I’ve been seeing this behavior for a while, not sure of the cause. One thing I noticed today is that ray1.9.1 on my mac shows the dashboard. Ray starts and tells me that the dashboard address is 127.0.0.1:8265

Ray1.9.1 on ubuntu 20.04 I get a connection refused (firewall not active) and tells me the ray address is 10.x.y.z:6379 but does NOT report a dashboard address

It seems that this issue has been fixed in Ray 2.0 with the new default dashboard. Let us know if you still running into this issue.

python3.10.10 ray 2.6.1 getting the same issue

Same issue here with Ray 2.7.0 and Python 3.10.12

I got this when I used the sample minimal AWS cluster config file, using Ray 2.13 and Python 3.11. I changed it to the sample full configuration, and everything came up normally. I think the minimal configuration example at Getting Started — Ray 2.31.0 is missing some necessary values (the full one is at ray/python/ray/autoscaler/aws/example-full.yaml at master · ray-project/ray · GitHub ).

This can happen when Ray head node is not started yet. If the head node is up and running I don’t expect this issue to happen. Can you check with ray status to see if it’s working?
