| Summary | 0003235: peer (at home) PD67 fails to connect | ||||
| Description | NAT is punched, so there is no good reason for this behavior. Failure to connect is at the transport level (I see at most 1 connection most of the time, rarely 2, rarely zero). | ||||

Manually creating a HELLO from the known data and importing it at pixel enabled pixel to connect instantly. After a while, we also then saw 'inbound' connections being active from PD67. So once OTHER peers have a VALID HELLO, the connection will be established. So: 1) maybe PD67 fails to create a proper HELLO (but then, it should still succeed connecting TO the other peer, even if it fails to receive inbound connections) 2) maybe PD67's timestamp in the normal HELLO is way off (but then, shouldn't the core connection also fail with signatures expired, etc.)? 3) maybe other peers somehow/somewhere reject (or at least fail to properly) incoming connections from PD67 and thus do not even get the HELLO; |

Seems to be much better now. There is still likely an issue with peers that are behind unpunched NATs, but at least the "easy" case is now working again. |
