unable to route payment to destination: TemporaryChannelFailure

Keep getting this error following attempting to pay an invoice. 

root@ubuntu-s-1vcpu-2gb-nyc3-01:~# lncli --network=testnet payinvoice lntb50n1pd65u8fpp5y0dwjcn6uhg05sla3djsa7h483nk07m5fs7v3qmnkcn37fq7n68qdqqcqzys98h745eywzuxcfa6c4avku3xzwxvjmfuvp3qe7r0ejnzt50vz3g565h83k56rz0l2v05575aj8x8738g2nnnm0zm26rgtg209ze2l0qp5gkdlc

    "payment_preimage": "",
    "payment_route": null
}

Both nodes are connected to the same node and should be visible to each other, however payinvoice always seems to fail due to routing.

What is causing this issue and how can I complete a payment correctly?

Get crypto-currency price at a timestamp without limits

I’m trying to get the price of a crypto-currency at a specific timestamp. So I used the API cryptocompare :

https://www.cryptocompare.com/api/#

For example :

https://min-api.cryptocompare.com/data/pricehistorical?fsym=ETH&tsyms=USD&ts=mytimestamp

This solution works well but I have some issues related to the limitation of the API.

I need to get the price more than 26k times and unfortunately this API won’t let me do as many requests.

It returns me this error :

{“Response”:”Error”,”Type”:99,”MaxLimits”:{“Minute”:300,”Second”:15,”Hour”:8000},”Message”:”Rate
limit
excedeed!”,”Aggregated”:false,”Data”:[],”YourCalls”:{“hour”:{“Histo”:16},”minute”:{“Histo”:16},”second”:{“Histo”:16}}}

Do you have a solution to avoid that ? Is there a way to get all the prices in only one request ?

Someone as mentionned that on reddit : https://www.reddit.com/r/ethereum/comments/6xbwxp/ethereum_price_history_api/

But I didn’t find how to do it.

Change derive path

I’ve used bitcoinj wallet and used derive path as below.

public static final ImmutableList<ChildNumber> ACCOUNT_ZERO_PATH = ImmutableList.of(ChildNumber.ZERO_HARDENED);

But I made changes in above path for generating bip44 standard addresses.

public static final ImmutableList<ChildNumber> BIP44_ACCOUNT_ZERO_PATH =ImmutableList.of(new ChildNumber(44, true), new ChildNumber(1, true), new ChildNumber(0, true));

Now As I load wallet in application then it loads from backup and app crashes because it took old derive path and I already changed it.

So it won’t find old derive path and app crashes.

How can I change derive path?

Please help.

Thanks.
