I’m attempting to fetch blocks utilizing P2P messages however at block 501500 I by no means acquired any block message.

Right here how I do it :
I’m connecting to a node model/verack occurs easily. I immediately reply any ping message. I’ve been in a position to do the getblocks/inv/block course of as much as to dam 501500 the place I’m at the moment caught. I haven’t got timeout so I’m simply ready for my block messages. I additionally observed I’m not receiving ping message anymore. May or not it’s that the node disconnected from me ?

Once I ask blocks from the beginning I’ve a solution. The node is meant to be synced as I get its begin peak from the model message and it matches present block peak.

Is there a purpose why the node is disconnecting from me ? Any concept how I may debug or repair this ?

Word: I additionally tried with completely different nodes however I by no means get the blocks.
