Error submitting message to hub: HubError: read ECONNRESET / Call cancelled

[eucalyptus-viminalis]

What is the bug?
Nodejs app fails to submit message using the public nemes.farcaster.xyz:2283 URL using HubRpcClient from @farcaster/hub-nodejs.

The error messages I'm getting:

• for makeUserDataAdd: Error submitting message to hub: HubError: read ECONNRESET
• for makeCastAdd: Error submitting message to hub: HubError: Call cancelled

How can it be reproduced? (optional)
This bug relates to the write data example in the hub-nodejs package. In my clone I am using the getInsecureHubRpcClient method to create the client using the public hub URL nemes.farcaster.xyz:2283.

Additional context (optional)
Add any other context about the problem here.

• I've checked that the public key of the signer corresponds to the one recorded onchain by the KeyRegistry contract.
• My feeling is that it's a problem with using the getInsecureHubRpcClient instead of getSSLHubRpcClient but I'm not sure if there is a username and password available to use with the public server.
• It seems I'm only getting this error for submitting messages. e.g. I can run the chron-feed example without any problem.

This isn't a bug—sometimes network connections fail. You need to design your application to be resilient to failure.

When such a failure occurs, try writing to another hub instead. Have your code gracefully failover to the other hub.

Okay so it's got nothing to do with how I was using the APIs? It was just that the nemes hub I was using was down or something?

But that doesnt make sense because as I said the chron feed which I was using the same hub URL for was pulling data fine 🤔🤔 I'll have another go and report back..
