I have problem with finishing sync of my Ethereum wallet. It stucks 100 blocks before the end, it´s trying to download long chain structure, but it stops every time at some point - on screen it stoped at 683391 of 687160. After restart, it runs again and it stops at some point again.

I haven´t find same problem in troubleshooting, so I hope this is not repost.

I´ll be very grateful for any advice.

Best regards,


  • This topic appears often here, you may want to read links to "go-ethereum". Also here: ethereum.stackexchange.com/questions/18709/…, and on github: github.com/ethereum/go-ethereum/issues/14571 - people are working on it, but no clear path to root cause analysis... Jul 20 '17 at 9:30

Try changing the internet time to "time.nist.gov". Control pannel--> Clock,Language...--> Date and time--> Internet time. For me it worked (it finish all the block and finally i can see my balance),but after some times is stuck again on the last blocks (180). I' ve done it yesterday. And i also run Geth before the ethereum wallet.


I ran into the issue as well trying to sync the main net on my laptop. After some research I found this explanation: https://github.com/ethereum/go-ethereum/issues/16251#issuecomment-371449572

Basically the issue for me was that my MBP has HDD and not SSD: It's apparently no longer possible to sync with the blockchain locally on HDD.

I ended up using the light sync mode : geth --light and so I was able to sync with the chain and deploy contracts etc.

Hope this can help
