-If you are having issues with certain widgets that are unable to reach public APIs (e.g. weather), in certain setups you may need to disable IPv6. You can set the environment variable `HOMEPAGE_PROXY_DISABLE_IPV6` to `true` to disable IPv6 for the homepage proxy.
-
-Alternatively, you can use the `sysctls` option in your docker-compose file to disable IPv6 for the homepage container completely:
-
-```yaml
-services:
-  homepage:
-    ...
-    sysctls:
-      - net.ipv6.conf.all.disable_ipv6=1
