Handle timeout

[avignat]

I had recently had a connection timeout with a partner.

The message status is in a error state and I can't retry it.

Is there more to the exception here because I cannot see the django-pyas2 code anywhere in this exception

@avignat : I do think the error is handled correctly. if that error occurs, the message should get the status "Retry". After the retries have executed, only then it will go to "Error". There was an issue with the count of retries (meanwhile fixed). Is my assumption correct, that you had retries for this message executed (maybe not the right amount of retries, but at least some)?

Then I would suggest to add a possibility to reset the "retry count" or some other option to trigger a retry of a failed message.
