Hi, do you have some more logging of what was going on before this exception happened?

[NektoDron]

It can't be fixed? Can you catch this exception to avoid the program crash?

[NektoDron]

I see the problem is that Reconnect method doesn't catch the exceptions though it's executed at the separated thread.

[JKorf]

Hi, can you try with the new version 1.2.2 which should be available in a few minutes? I fixed some bugs there.

[NektoDron]

It works fine already for a couple of days.

Hi, I've pushed a new version 1.2.3 that should fix this. Sometimes the socket of the underlying websocket library I use keeps hanging in the connecting state which causes this problem. New version creates a new socket when trying to reconnect so that should fix it.

[JKorf]

That's weird actually, as it makes a new socket when reconnecting. Could you maybe turn on Debug (LogVerbosity.Debug) logging and share the logging of when/before this happens? Appreciate your help trying to figure this out..

[jojotutorial]

I think I have experienced a similar issue here. nothing happened before but the socket suddenly shut down and keep reconnecting itself but failed.

Actually, I am running two programs at the same time using the same key pair, the program starts normally at the initial state but one of them would be crashed with the following error a few hours later. Does error have somthing do with this?

Thanks in advance!

[jojotutorial]

On top of my last observation, it keeps saying that there is a "process loop ended" and "Authentication failed: nonce: small" issue.

May I ask what is the process loop about?

[JKorf]

The process loop is the thread that process all incoming messages. If you get the message that it's ended it means the thread is ending. It's normal when restarting the connecting. In the previous post you said you have 2 programs running which connect to the bitfinex server, this would explain your issues with nonce: small. The reconnecting issue is interesting..

It says 0 subscriptions to resend, did you actualy have subscriptions running when the reconnections started, do you also have logging of when this started? And I assume you're on the latest version? (1.2.4 atm)

Thank you @JKorf .

And I assume you're on the latest version? (1.2.4 atm)

yes I am using the latest version

In the previous post you said you have 2 programs running which connect to the bitfinex server, this would explain your issues with nonce: small.

Yes, you are right. This happened when the same pair of listen key is used in the parallel programs. I resolve this issue by using different pairs of listen key in the parallel programs and now they work fine. :)

The reconnecting issue is interesting..It says 0 subscriptions to resend, did you actualy have subscriptions running when the reconnections started

yes I subscribe to the wallet, order and trades update once the connection is made....But once the connection is restored (refering to the previous post, I could detect the restore Action that you designed, and I print the line "INFO Connection Restored" myself), the socket closed very soon after around 20 sec. I workaround a bit by detecting the change of socket state: when "Disconnected" was detected, I restart the whole socket on my side.

your wrapper is great though! :+1: Can't wait to see more works on other exchanges (e.g. Huobi) from you ! ^^

[JKorf]

Thanks for the kind words ^^ I'm a bit busy atm, but the next exchange up would be Huobi.

Back to the problem, at some point the socket disconnected and didnt resubscribe the existing sub after reconnecting. Do you by any chance have logging of that point?

Btw, version 1.2.5 is available, it fixes an issue with sometimes missing the first message after subscribing.

I am much appreciated for your effort, and I have recommended these to my friends!!! I also see a few potential exchanges such as Huobi and Gemini, do you have plans to develop them as well?

[JKorf]

Thanks :) I'll probably do Huobi as well as multiple people have requested that but I don't want to make any promises if or when that would be ready.

On topic: If this problem still exists please open a new issue and provide new logging.
