"Not enough funds" in Electrum (3.0.1/OSX) wallet

[dlezhnev]

Hi!
This is my situation:
- I made a new wallet in Electrum wallet;
- Exported xpub address and generate few sub-addresses;
- Accepted funds on those addresses;
- I can see confirmed incoming transactions in Electrum, as well as total Balance, shows a correct amount.

The problem is that when I click "send" and try to transfer accumulated funds somewhere else it says "Not enough funds".  

How can solve the problem and send my funds?

--
The reason was that Electrum did not show which fee amount it has set. So switching to manually setting fee size solved it.

Are you using the Electrum wallet with segwit option? or you still using the legacy wallet?

Here try to use the old version of electrum wallet instead from here https://download.electrum.org/

And try to send bitcoin again.

Can you click "preview" instead of send... and tell us what the reported "transaction size" is (in bytes) and how many inputs are being used... also, how much BTC are you attempting to transfer?

It's possible, that if you have received a number of small "dust" sized inputs, when you are attempting to transfer your funds, the data size of the transaction has been made so big due to a large number of inputs, that the dynamically calculated fee is bigger than your total available balance.

It's also possible that you're attempting to spend "unconfirmed" inputs... and your Electrum is not configured to allow this (Tools -> Preferences -> Transactions -> "Spend only confirmed coins")

Worth mentioning for everyone who uses Electrum.
