Stuck after running node (moved from incorrect category)

Hi all,
I’m new to linux and node-building and trying to figure all of this out. I keep getting stuck in the stake pool course at the point after I’ve gotten configuration files and go to run my node for the first time. It looks like it starts syncing to the blockchain, but then I keep getting errors and warnings as posted below. Any help on what I may be doing wrong would be greatly helpful. I’ve tried starting over form scratch multiple times now.

It looks like I’m having an issue with the iohk dns where their relays are listed? Please help!

Could be an issue with IOHk relays; if u have more peers and your nodes are still syncing there should not be any problems…
