ERROR:cli.py:722:Connection unexpectedly closed #266

Open MatthK opened 3 years ago

I have installed the dockerized version. It initially worked, but any subsequent reports that came in didn't get processed anymore.

And now I just keep seeing this error in the log file:

0it [00:00, ?it/s]
0it [00:00, ?it/s]

   ERROR:cli.py:722:Connection unexpectedly closed

I was assuming that it might be a connection issue to get the email, but they do get transferred from the inbox to the aggregate folder.

Any idea what that could be?

I did a bit more digging. I looked at 258 and suspected this could be my issue as well. Especially since I did have some strange error messages in the SMTP log file.

09/02/21 15:19:51   [1380] SSL recv failed: 10060.
09/02/21 15:19:51   [1380] SSL_Handshake negotiation failed
09/02/21 15:19:51   ME-E0xxx: [1380] SSL Handshake failed. Closing connection.

So I changed the parsedmarc.ini file to not use SSL and restarted that container. Now the SMTP log does not show those SSL_Handshake errors anymore, while the log of parsedmarc now shows a Connection timed out error instead of a Connection unexpectedly closed error. Progress, but not a solution.

Unfortunately I could try the proposed solution from 258, as I can't get into the docker container and adjust the code.

Yet another update. I did find a way to get into the docker container, and amended cli.py with the suggested changes from 258. After a restart of the container, the Connection timed out error is gone. And shortly after the restart, I did receive an email with a ParseDMARC Report.
