Could be? I don’t have rpi5 at hand, but docker run --rm -it --net=host ipfs/kubo:v0.33.0-rc3 works fine on rpi4.
Would be good to have someone with rpi5 to confirm if they have similar issue, until we have second data point from other rpi5 user, this looks more like something specific your network setup somehow.
All or just WAN? Are you able to dial Raspbery PI Peer from within LAN?
Try vole:
$ vole libp2p identify /ip4/LAN-IP/tcp/4001/p2p/12D3XXXXXXXXXXXXXXXXXXXXXXX
Try 0.33.0-rc3 with ipfs config --json AutoTLS.Enabled true
AutoTLS will enable additional transport for browser-based clients like inbrowser.link.
