Can not reach stats server from my 44net /24

I have 3 operational nodes, a hub node 45977, a home node 48223, and a portable node I use when camping 44170. All 3 nodes live on my 44net /24 (44.30.42.0/24) - the home and portable nodes have connectivity over VPN, while the hub is directly connected.

None of these nodes are able to post stats to stats.allstarlink.org:

[2025-10-02 20:45:04.569] WARNING[51527]: app_rpt.c:1030 perform_statpost: statpost to URL 'http://stats.allstarlink.org/uhandler?node=44170&time=1759455774&seqno=11591&nodes=T45977&apprptvers=3.5.5&apprptuptime=346959&totalkerchunks=11&totalkeyups=13&totaltxtime=51&timeouts=0&totalexecdcommands=1&keyed=0&keytime=52' failed with error: Failed to connect to stats.allstarlink.org port 80 after 130199 ms: Couldn't connect to server

Indeed, none of the 3 nodes can ping the stats server either. But from my desktop, which uses my home provider and not 44net, I can successfully ping the stats server. Also, directly from my router which announces my /24 (but does not use one of those IPs), I can also ping stats.allstarlink.org.

Is there any filtering on the stats server that would prevent the use of valid 44net IPs that are announced over the internet?

No.
