Hello. I just upgraded Mobilizon to the latest release and all the account avatar images are blank

In reply to @javahippie:freiburg.social
How are you running it, Docker, from source…?

In reply to @juasmis:matrix.org

Hello again, first a summary of how far I've got so far:

1. Setup exim in a docker container
2. I can send mails from this container

1. Setup exim in a docker container

I've based myself in devture/exim-relay, but modified the conf file (find attached its configuration)

Dockerfile

FROM docker.io/alpine:3.20.2

RUN apk --no-cache add exim tini && \
    mkdir /var/spool/exim && \
    chmod 777 /var/spool/exim && \
    ln -sf /dev/stdout /var/log/exim/mainlog && \
    ln -sf /dev/stderr /var/log/exim/panic && \
    ln -sf /dev/stderr /var/log/exim/reject && \
    chmod 0755 /usr/sbin/exim
RUN apk --no-cache add openssl

COPY exim.conf /etc/exim/exim.conf

# Regardless of the permissions of the original `exim.conf` file in the build context,
# ensure that the `/etc/exim/exim.conf` configuration file is not writable by the Exim user.
# Otherwise, we'll get an Exim panic:
# > Exim configuration file /etc/exim/exim.conf has the wrong owner, group, or mode
RUN chmod 664 /etc/exim/exim.conf

# Generate certificates for TLS
RUN openssl req -x509 -sha256 -days 9000 -nodes -newkey rsa:4096 -keyout exim.key -out exim.crt -subj "/CN=exim-relay" && \
    mv exim.crt /etc/ssl/exim.crt && \
    mv exim.key /etc/ssl/exim.key

USER exim
EXPOSE 8025

ENV LOCAL_DOMAINS=@ \
    RELAY_FROM_HOSTS=10.0.0.0/8:172.16.0.0/12:192.168.0.0/16 \

    SMTP_USERDOMAIN= \
    SMTP_USERNAME=

ENTRYPOINT ["/sbin/tini", "--"]
CMD ["exim", "-bdf", "-q15m"]

docker-compose

...
services:
exim-relay:
    container_name: mobilizon-exim-relay
    # image: docker.io/devture/exim-relay:4.98-r0-1
    build:
      context: ./exim-relay
      dockerfile: Dockerfile
    env_file:
      - ./exim-relay/.env
    user: 100:101
    restart: always
    networks:
      - default
    ports:
      - "25:8025"
    environment:
      HOSTNAME: external.psa.es
      SMARTHOST: correo.psa.es::587
      SMTP_USERNAME: username@psa.es
      SMTP_PASSWORD: password
      SMTP_USERDOMAIN: psa.es

2. Veryfied that I can send mails from this container

echo -e "From: username@psa.es\\nSubject: test" | docker exec -i exim-relay-mobilizon exim -v jmserrano@psa.es

Does send the test emails as can be seen in the attached picture.

I think so far I managed to get the forwarding part correctly, now it only remains the mobilizon side of things, so far no lack. This is my compose, .env and config.exs:

Same unhelpful log message, also can't see anything in exim container logs:

I feel like I am getting there, if you guys can help me I would really appreciate it!
