ActionCable not working about kamal

[initseis]

I think ActionCable failed when I upgraded from 7.0.6 to 7.1 so I had to start a new project and copy all my files and now it is working.

I encountered the same error and was able to resolve it by setting allowed_request_origins in production.rb as follows:

config.action_cable.allowed_request_origins = ['https://rubyonrails.com', %r{http://ruby.*}]

ActionClable permits connections from specified origins. For more information, see the Ruby on Rails Guides on Action Cable. https://guides.rubyonrails.org/action_cable_overview.html#allowed-request-origins
