I sent out a payment in electrum v1.9.8 and I checked blockhain.info and it says the transaction was rejected by the node because of Non-canoical signature: High S Value. I upgraded to v 2.6.4 and I am connecting to electrum.de server running bit v0.12 but the transaction is still unconfirmed in electrum.

Transaction id:
a667e6d1a80c17bd0b55afec7c6ec618ca64a2a6c1b4f9badaf1c883bf5cb5dd

Any thoughts?
