Gets stuck in this error loop: Error: <urlopen error [Errno -5] No address associated with hostname> Requesting returnActiveLoans #251

Closed taw00 closed 7 years ago

taw00 commented 7 years ago

I have not put my finger on this yet, but I have to periodically restart lending bot (I use systemd) because it seems to have a network issue(?) and then never recovers(?).

I am not sure if other people are seeing this. I will continue to troubleshoot and see if I can determine what is going on. Maybe it is me, but it seems like that connectivity and recovery from connectivity issues is not robust.

By the way, love the tool in general.

Why do you assume it doesn't recover? The bot reports errors than sleeps and continues...

taw00 commented 7 years ago

After watching this for awhile... It does eventually recover. It's just that the error is managed and messaged ungracefully. Tracebacks should only happen when things break, not for normal connection statuses.

Closing. The devs know about this... It works "well enough".

rnevet commented 7 years ago

I agree, we are trying to handle communication​ errors and poloniex errors more gracefully... It's a work in progress.

@taw00 This is handled in https://github.com/Mikadily/poloniexlendingbot/pull/260
