Could not propose DLC channel: Wallet error Wallet does not hold enough UTXOs

[holzeis]

Even though the coordinator has enough utxos (and funds) it happens now frequently that the coordinator still fails to propose a dlc channel.

Built a tool to check the coin selection locally with the prod seed, but couldn't reproduce the error. Michael eventually succeeded, but I can't say why.

@bonomat @luckysori I've also assigned you to this ticket since all of us have been working on this so far. Any ideas what we could do next?

My only direct experience with this problem was solved my doing a full sync.

My first few attempts at doing a full sync failed because I misinterpreted the API and thought it accepted a JSON body. For reference, this is what the request should look like to trigger a full sync:

curl -X POST "localhost:8000/api/admin/sync?full=true&gap=200"

What do you think of allowing to specify the wallet seed separately to the coordinator and then switch on-chain wallets once in a while to reduce the gap we have to carry forward?
