No 'News' or 'Featured Content' feeds

[double2zero]

When I run the image under Portainer, on a Raspberry Pi 4 (4GB), I do not get any content in the 'News' or 'Featured Content' feeds. Instead I get red errors: 'No content recommendations were received from the foundryvtt.com web server.'

Additionally, I am unable to search for modules directly within the server web interface, experiencing a timeout (I can install modules via the .json link fine, once I have that from the foundry vtt site):

I am running the container under Portainer, with the following compose:

---

version: "3.8"

services:
foundry:
image: felddy/foundryvtt:release
hostname: foundry-vtt
volumes:
- type: bind
source: /my/data/location
target: /data
environment:
- FOUNDRY_PASSWORD=MY_PASSWORD
- FOUNDRY_USERNAME=MY_USERNAME
- CONTAINER_PRESERVE_CONFIG=true
- FOUNDRY_SSL_CERT=MY_SSL_CRT
- FOUNDRY_SSL_KEY=MY_SSL_KEY
- FOUNDRY_TELEMETRY=false
ports:
- target: 30000
published: 30000
protocol: tcp
restart: unless-stopped

I should say that, this issue aside, the server runs extremely well, 24x7, with multiple users per weekly session. Any assitance is greatly appreciated.
