Error pay invoice. Ran out of routes to try after 2 attempts: see paystatus

Question

I wanted to send some satoshis on testnet lightning network but I got "Ran out of routes to try after 2 attempts: see paystatus" error.

I have a channel with 02...48 (1ML.com node ALPHA) and created the invoice on starblocks.acinq.co.

I think the error was caused due to path finding error but how can I solve it? What is this situation? Do we need to connect another peer and fund it again?

I use c-lightning v0.7.0

I'm now trying to "see paystatus" but no idea now.

Update 3

I tried it again then it worked.

Before doing that I deleted my lighting data folder and restarted it. Then I did the same process as the previous one.

One different things is that I connected another node because building node topology was stopped. (I got not found route error)

I don't know why I got the error at the first time. The lightningd is running in docker in my local Mac so I think this might be the cause...? (not sure but it could be being sleep mode after connecting channel.)

Anyways, the problem was solved. thank you.
