Same here. Any solution?

#432 maybe you can see this issue.

[qianlong0502]

Adding --host 0.0.0.0 may solve your problem.

[mpetruc]

--host 0.0.0.0 does seem to be solving the problem. maybe the instruction on the main page should be updated to include this solution: python3 -m fastchat.serve.controller --host 0.0.0.0

Google Colab redirects localhost to the VM backend, using 127.0.0.1 solves the issue:

!python3 -m fastchat.serve.controller --host 127.0.0.1 --port 8000
