I am trying to catch up/synchronize the blocks in my blockchain with bitcoin-qt. However, the last block time is stuck for hours at Feb 15 04:29:18 2017 since I started bitcoin-qt the last time.

enter image description here

What is the reason?

The debug.log doesn't show anything supsicios.

When I start bitcoin-qt with -testnet, it does catch up.

Appendix, as per Pieter Wuille's comment, the output of getchaintips is

[

    "height": 473710,
    "hash": "0000000000000000007eaaf0899877f5317cd2a480477bde88d9e0a9b57a93c8",

  • Can you post the output of the getchaintips RPC? This will not reveal any private information, just a list of which chain forks your node knows about. – Pieter Wuille Jul 1 '17 at 17:06
  • @PieterWuille I've added the getchaintips output. – René Nyffenegger Jul 1 '17 at 17:24
