Connection refused #14

Closed quartox closed 7 years ago

quartox commented 7 years ago

I believe the servers that I use will not allow launching of connections to localhost. Instead you need to specify the full host name. E.g. when launching jupyter I use socket.gethostname() as the IP.

I believe the following error is related, but I am including the full error trace in case I am misunderstanding.

Error in atexit._run_exitfuncs:

Did you successfully start a session before seeing this? atexit only appears in the codebase as a terminator for dask_yarn, it would be strange if you could start containers but not stop them...

quartox commented 7 years ago

My most recent errors are in #17, so I haven't seen this in a while. I saw this error message before #13 was fixed. I haven't seen it again, but I am not sure if it would be an issue for future users. Feel free to close if you don't think it is a concern.

martindurant commented 7 years ago

I'll close then, and can be reopened if this specific thing emerges again.
