Liveview hangs on initial page loads but then works normally

Hello

with LiveView 0.12, with poor internet connection, I experience websocket timeout error on initial page load,
but after that liveView works normally.

after a page reload again a very long time with hanging spinning wheel, and then liveView behaviour works
normally.

What could cause that ? is there a way to reduce the timeout on initial connection ?

thanks

Do you see any errors in the javascript console or in your logs?
