Unable to broadcast transaction. Payments will not send


In electrum 5.0.1, 5.0, and 4.0.1, I am unable to send a transaction.

I select the amount, send, its signs, and then in the bottom left corner it just says" Wallet total (xxxamount of smart)unconfirmed", for some time until it eventually clears the mempool, and never sends. After I send the payment, it does not show up in my transaction history, only the bottom corner where it displays my wallet amount and the unconfirmed amount total.

Any help would be appreciated, I’ve been trying to send my SmartCash to sell it for some time now, but have been unable to get it to send from my wallet.
