Perhaps Firewall related issue, like on my test system.
No ssdp message is received when firewall is enabled.

Even with socat:

socat UDP4-RECVFROM:1900,ip-add-membership=239.255.255.250:0.0.0.0,fork,reuseaddr -

After disabling the firewall, it works.
OS: CentOS 8 Stream

Something to read:
https://unix.stackexchange.com/questions/19060/fedora-firewall-with-upnp
https://unix.stackexchange.com/questions/625969/upnp-with-firewalld

TODO:

Test on local prod system (Rocky Linux 9.1, firewall disabled)
Same shit, as on test
Document firewall rule to fix this
firewall-cmd --zone=public --add-port=1900/udp
