Moved to RPi5, cannot connect or download anything - skipping tracker announce (unreachable)

[mjb141]

Had Deluge running on RPi4 for years fine. Moved to RPi5 today, same settings, can't connect to anything, can't download anything.

Deluged 2.0.3
libtorrent 2.0.8.0
Python 3.11.2
OS Linux Debian bookworm

Inbound port set to 16881, router firewall set to allow 16881 tcp/udp to this device and router correctly identifies the device by IP (which is reachable in web UI on that same address).

Netstat shows 16881 listening on TCP. Canyouseeme.org still shows port unreachable despite deluge daemon running, webui showing it running, torrents being added (and stuck at 0.0 skipping tracker announce).

ipconfig.me returns an IPv6 address, and incoming addresses in Deluge is blank. Do either of these points matter?

What am I missing?

Hi,

Can you turn off deluged with systemd unit file. Then backup your config files by renaming them to for example core.conf.bak. Then start deluged again. This will create new config files and then start testing if you are able to download it. Off course change the basic network settings (the port for example that you use for portforwarding).

I had similair problem in the past. After letting deluged create new config files, everything worked fine again. Off course i had to configure the settings again (but i had the old config files backuped, so it was just compare and change).
