I think what’s happening here is an incompatibility because the signet Ark server is running beta.7 which is about 4 weeks old and I’m pretty sure we’ve made breaking changes since then. We don’t handle incompatibility very well right now and it’s something we’re looking to improve for mainnet. Would you mind testing with beta.7 and see if it works?
