i try now for a long time, to download and install the IDS Rules for Suricata in the newest OPNsense.
Here is a log:

download failed for https://rules.emergingthreats.net/open/suricata-7.0/version.txt (HTTPSConnectionPool(host='rules.emergingthreats.net', port=443): Max retries exceeded with url: /open/suricata-7.0/version.txt (Caused by ConnectTimeoutError(<urllib3.connection.HTTPSConnection object at 0x845b78390>, 'Connection to rules.emergingthreats.net timed out. (connect timeout=None)')))

Other things like updateing the Firware has success. Only the download / install from the rules.
I allow 443 at my firewall and i cant see a error at the firewall logs.
