The I/O operation has been aborted because of either a thread exit or an application request

[scholes88]

Describe the bug Get latest master, build myself, run with ethermine pool, got this error: X 18:08:06 stratum Error [2606:4700:90:0:5f75:d2fd:8cfe:d849]:4444 [ The I/O operation has been aborted because of either a thread exit or an application request ]

To Reproduce Seems like related to environment, I use the same executable to run in another environment and everything works fine. I'm trying to understand why this error happens.

Expected behavior It should work.

Desktop (please complete the following information):

• Operating System: Windows 10
• Hardware Quadro K2200
• Ethminer Version 0.17.0-alpha.1+commit.b1055ca3

Additional context I tried debug a little bit, it seems like the problem is in EthStratumClient.cpp -> line: 526 connect_handler(). The ec is "The I/O operation has been aborted because of either a thread exit or an application request". Host resolver works fine. I've tried to change all different protocols (Stratum123 + tcp/ssl/tsl12), other pools, all failed in same place. Searching online doesn't help. I've also tried other miner programs on same machine, e.g. finminer, it works fine. If I use same ethminer.exe and run on an different machine (with different network), it works fine too. So probably related to some configurations that specific to this machine. Does anyone know what could be the problem?

It's highly probable your network adapter does not have an IPv6 address.

[scholes88]

I've tried with ipv4 address directly, it's failing with same reason.

Can you please post a trace log longer than that single line ? When does the error happen ? Immediatley at connection or after some time ? Is Windows firewall disabled ?

[scholes88]

The firewall has been disabled, it failed immediately at connection.

I have received this error by using the incorrect stratum protocol. Try using stratum1+tcp:// or stratum2+tcp://

[AndreaLanfranchi]

I think the key factor is this

If I use same ethminer.exe and run on an different machine (with different network)

Probably you're on a network you do not control with a firewall at gateway which blocks comunications on not well known ports. (maybe work office ?)

Closing by know as we have no evidence and the error clearly states ethminer can't establish a connection with remote endpoint.
