@PedityOfficial Thanks for filing an issue.
Kelp operates under the assumption that the horizon server you provide will always be available. From your logs, it seems that the timing of when you faced the error coincides directly with when public horizon was down yesterday, causing your bot to crash. The behavior of the bot is unpredictable when it cannot reach horizon for now -- a crash is not surprising in such a case. This is definitely an issue, one that will be addressed in due time.
It is rare that public horizon is down and it's unfortunate that this rare event occurred only a day after you started Kelp. I'm not expecting you to see this issue again if public horizon remains stable.
I'm closing this issue for now since it's something we'll be working to fix soon. Feel free to re-open if you see this issue again.

why not just catch the error and try again at the next timeout interval? Crashing seems unfriendly.

@nikhilsaraf , This issue happened again and as you said I am asking you for reopening this issue :)
I agree with @skirsch solution and there can be more possible solution as well. Hoping to see this gets fixed.
