sse client can't connect sse server. run sse client following sse/client. run sse server following example-servers/everything.

Hi, I can confirm. Upgrading from 0.23.0 to 0.25.0 (Same for 0.24.0) result in 404 when the client is trying to connect with the server.

Any updates on this one @ezynda3 ? Thanks.

Hi. I just added a sample client to main to help test things like this. With the most recent code v0.26.0+ clients seem to connect just fine.

Thanks for confirming that @StarpTech, I'm going to go ahead and close this for now.

Happy to reopen though if we've misunderstood something.
