Same as Problems with Identicon/Gravatar (ConnectionResetError(104, 'Connection reset by peer')) - but you need to set these env vars in the indico-celery systemd service unit as well; otherwise the scheduled background tasks won’t use your proxy.

Sorry for the additional trouble :slight_smile: i am a Student and just started to get the gist of everything.

So the same env Variables in the /etc/systemd/system/indico-celery.service file under [Service]?

Yes:

Environment="HTTP_PROXY=http://ourproxy:8080"
Environment="HTTPS_PROXY=http://ourproxy:8080"

Then systemctl daemon-reload and systemctl restart indico-celery.service.
