#5457 Unable to accept a subscription request
Closed: Fixed None Opened 5 years ago by shnurapet.

I am managing the trans-ru@ mailing list and I'm being unable to accept a person's subscription request due to an error. "The request could not be moderated: A server error occurred. Please contact the administrator." The list is on the "confirm, then moderate" subscription policy.

When this issue occurs, the following comes up in /var/log/mailman3/mailman.log:

Sep 04 14:21:45 2016 (15656) - - "GET /3.0/lists/trans-ru.lists.fedoraproject.org HTTP/1.1" 200 370

There are currently two pending subscription requests, could you tell me which one is causing the error? (I don't want to try and accept a subscription requests without your consent)

It's the one @gmail.com.

The cause for this was more complicated than anticipated, I've submitted a [https://gitlab.com/mailman/mailman/merge_requests/190 patch] upstream and deployed it. I've also accepted the corresponding request for you, so you don't have to do it.
