Connection attempt fails

pharazen commented 5 years ago

After the latest commit I am able to successfully connect to myself on localhost. However when attempting to connect with another user we both simply get:

Received event ConnectFailure(PeerId {.........key data here........}) (not handled)

Is there some way to debug further? The only thing I know is it's a connect failure. I guess it's timing out?

Let me be clear that we did follow (i think) the expected process:

1) User A and B both call prepare-connection-info and exchange the key 2) User A enters connect 0 {User B data} 3) User B enters connect 0 {User A data}

Then nothing happens for about 10 seconds, and it gives ConnectFailure (not handled)

Still unable to debug this, any ideas?

Hi @pharazen I'm just testing this now so I'll get back to you with my findings

Progress update on where I've got to with this...

I was able to connect two peers from different networks to each other by manually opening the relevant ports on the routers that the peers were listening on. Note that I also had to edit the "for_direct" section of the connection info before pasting it into the other peer, as I only had internal IPs, so I added the external IP and port number. Connection successful.
If UPnP is enabled on the 2 peer's routers then as far as I understand, you should be able to connect without port forwarding, as this should take care of it for you, but UPnP does not work on the 2 routers I have access to. I'm hoping to rope a couple of others who have routers with working UPnP into helping me verify this tomorrow. Will update this issue accordingly.

Note that I'm assuming you are behind a NAT, as I am.

Update - apologies, I've had no bandwidth to get back to this as yet due to other work taking priority.
