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.

@PieterWuille I've added the `getchaintips` output.

# bitcoin-qt does not add blocks anymore

(Asked by: username_0 on 2017-07-01)

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.

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 *username_1 username_1's* comment, the output of `getchaintips` is

```
