What version of lnd are you running?

Did you confirm that you have the funds available and confirmed with lncli walletbalance and lncli listutxos?

Sometimes utxos are reserved, did you try restarting lnd?

[philipp1992]

yes i can confirm that funds are available
its 0.14, restart doesnt help

[sputn1ck]

Ah I see, I think your issue might be related to the recent bug in the btcd script library.
Upgrading to lnd 0.15.2 will probably fix your issue

[philipp1992]

can confirm we are hitting this bug. thanks
