Sadly some relays or even nostr:npub1w27mc4aa6m0ufe3xs5z3m6qyr52gc0rglept7vqlwx4xeaf72tasnqz70r have an issue with Mullvad connections. I can't reliably zap when behind a proxy 😐

Try nostr:npub1jluy3twvf338v6zlujzzdhjkzjy8ezj34ksydr8vw8a6jwp89ygshpp2kq. It's ok to use a burner email address when making the account, no worries.
