Admittedly I am not using the latest master, so it's possible this issue has been fixed, but I suspect not, given that no other issues were raised for this issue.

Expected behaviour

expected a connection to succeed

Steps to reproduce

by running the addnode command within the CLI

How did you obtain Bitcoin Core

Compiled from source

What version of Bitcoin Core are you using?

v22.99

Operating system and version

Ubuntu 22.04 LTS

Using the list of nodes in #23018

expected a connection to succeed

I don't think expecting being able to connect to some 2 year old list of (random) nodes is exactly reasonable.

Do you have other I2P connections working? If not, you may need to restart (or upgrade) your I2P router. What router and version are you using?

Some of the nodes no longer exist, but I'm connected to several of them right now. If you're looking for seed nodes, try the ones in contrib/seeds/nodes_main_manual.txt.

I'm using the latest version of the i2p router that comes with Ubuntu 22.04 LTS.

Given this has been closed as "not planned" I'm going to assume I2P functionality isn't planned to be working and therefore will disable this from my node's configuration.

@rebroad, the seeds in contrib/seeds/nodes_main_manual.txt on master should be working, as are many of the ones you tried unsuccessfully to connect to. If you cannot make a connection, try restarting your router, upgrading your router (it can make a difference to use recent versions), verifying if you customized your router conf settings, or changing your router (to either i2prouter or i2pd).
