Dmarc2logstash fails to log in to outlook365 mail account

[fribse (Kenneth Fribert)]

I've had this running nicely, the dmarc2logstash runs, and pulls all the reports, unzips, and places them ready for filebeat to grab, and send to logstash.
I've used the code from jertel: https://github.com/jertel/dmarc2logstash

But now I get this shown in the log:

I've tested a login with a client using the name and password from the docker-compose config, and that works perfectly.
It was working a few months back, and I haven't checked up on it in while, but now I just see this message.

The config in docker-compose looks like this:

  dmarc:
    image: jertel/dmarc2logstash
    container_name: dmarc
    volumes:
      - ./dmarc/logs:/logs
      - ./dmarc/dmarc2logstash.json:/opt/dmarc2logstash/dmarc2logstash.json
      - ./dmarc/dmarclogs:/dmarclogs
    environment:
      - POP3_SERVER=outlook.office365.com
      - POP3_USERNAME=uh-oh-secret-hu
      - POP3_PASSWORD=uh-oh-even-more-secret
      - DELETE_MESSAGES=1
      - JSON_OUTPUT_FILE=/dmarclogs/dmarc.log
    restart: always

  dmarcfilebeat:
    image: docker.elastic.co/beats/filebeat:6.5.1
    container_name: dmarcfilebeat
    volumes:
      - ./dmarc/dmarclogs:/dmarclogs
      - ./dmarc/filebeat.docker.yml:/usr/share/filebeat/filebeat.yml:ro
      - ./dmarc/logs:/logs

Anybody that has an idea, Jertel maybe?
