The nodes list on the first post is pretty up to date.
But if you're using the newest wallet version, it should auto-create a conf file and populate it with good nodes/values.

I would first try closing the wallet, reopening it and giving it some time. (As in hours, not minutes.)
If that doesn't seem to work, you can check/try two things.

• 1) See how many connections you seem to be getting (mouse-over the signal-strength looking icon or use CLI command getconnectioncount).Over ten you should be fine.
• 2) You can consider trying the bootstrap. There is a link to it on the website and if you visit the Discord and search for the term "bootstrap" you will find several example instructions.

If you're still having trouble, feel free to give more details here or for quicker responses visit our Slack or Discord.
