connecting to convex via node daemon

So this possibly sounds backwards, but I've written a daemon that connects to the convex ecosystem. The main reason why is it's dealing with largish files and I was learning convex at the time, so wasn't sure whether I wanted to port it to the convex backend. It's been working fine, but due to another project, I've not touched it for a couple of weeks. So back to it and I'm having trouble with the service connecting to convex. I've been using convex/browser which has been working fine and I've got it running on remote linux servers with prod currently fine. But dev, just refuses to connect:

It should give me another message if there was a successful connection, so I know it's definitely not connecting at all. The way I'm connecting is:

import './env'

import { ConvexClient } from 'convex/browser'

const convexUrl = process.env.CONVEX_URL
if (!convexUrl) {
  throw new Error('CONVEX_URL environment variable is not set.')
}

console.log('connecting to ', convexUrl)
const client = new ConvexClient(convexUrl)
export { client }

import './env'

import { ConvexClient } from 'convex/browser'

const convexUrl = process.env.CONVEX_URL
if (!convexUrl) {
  throw new Error('CONVEX_URL environment variable is not set.')
}

console.log('connecting to ', convexUrl)
const client = new ConvexClient(convexUrl)
export { client }

with client.onUpdate calls:

 client.onUpdate(
    api.analysis_requests.getRequestsByStatus,
    { params },
    callback
)

 client.onUpdate(
    api.analysis_requests.getRequestsByStatus,
    { params },
    callback
)

Also added verbose logging and I get this:

Has something changed that could be affecting this? I did notice the DDoS attack a couple of days ago - maybe this is linked? I've also verified on a different network, so don't think it's a network issue. This is from my mac, which can connect via a browser fine. Looks like this is related to a node version issue - v18 works okay, but anything above that fails to connect.
