I am experiencing this problem in Safari Technical Preview 15.4, release 135.

In my case, attempting to open a WebSocket connection to a server with a literal IPv6 address fails with

    WebSocket network error: The operation couldn’t be completed. (kCFErrorDomainCFNetwork error 1.)

The address is ws://[::]:3589, which Chrome connects to without error. Safari succeeds when I use the equivalent IPv4 address, ws://localhost:3589.

The reason I ran into this is that I am attempting to debug a web application on my iPhone. I am serving the application from my laptop, which is connected to my phone via a USB personal hotspot. This hotspot only assigns my laptop an IPv6 address. I do not think I can alter my phone's /etc/hosts file to give my laptop's IPv6 address a domain name, so I am forced to use an IPv6 URL.
