I can see a Stagnet transaction from one of my wallets to another has succeed using https://stagenet.xmrchain.net, (with over 11 confirmation). but neither of my GUI wallets say it went through -- in fact the sending wallet says the transaction has failed.
I'm connected to the remote node: monero-stagenet.exan.tech over port 3801.
I've closed and re-opened the GUI wallets, but the discrepancy remains.
