Good day Bitcoin community, I hope y'all are having a great day.
uhmmm, i don't know if this is the right place to post this, but if it isn't pls pardon me, I'm still tryna get a hand of the forum.

So I'm tryna set up my own LND but i seem to have run into a bit of a problem (i at least feel it is) when i check my logs or start the terminal, it runs for a while and then the next thing i see is this endless log of warning  
Code:
[WRN] BTCN: unable to lookup IP for mainnet1-btcd.zaphq.io: lookup mainnet1-btcd.zaphq.io: no such host 
.    I don't really know but the node seems to stay online, synced-to-graph's true but I'm worried the recurring warning means my LND isn't actually broadcastable to the network or maybe my p2p discovery is broken. so is this normal? i need help please from the techies here.




PS: I'm running on an old Mac, if that helps...

I think you should rather move your topic to Bitcoin Technical Support. It belongs there if you have some technical issues with a node than in this section where the technical discussion is more in general about the Bitcoin network, its clients, ...

I don't think your issues fits this board's description:
Quote
Technical discussion about Satoshi's Bitcoin client and the Bitcoin network in general. No third-party sites/clients, bug reports that do not require much discussion (use github), or support requests.


Also, please provide more details. What did you install specifically, did you follow an installation recipe, if yes, which one? Imagine someone who wants to help you and ask yourself if you provided them enough details to grasp and understand your setup.

How is your (old) Mac connected to the internet? Is this connection stable? Does your network have any firewall or other stuff that could block things.

Your screenshot is basically unreadable small. You could post a thumbnail that links to a larger screenshot which doesn't require eagle's eyes. talkimg.com as forum's prefered image hoster gives you all such options easily.

[WRN] BTCN: unable to lookup IP for mainnet1-btcd.zaphq.io: lookup mainnet1-btcd.zaphq.io: no such host
Based from what I can perceive from the screenshot, the error isn't limited to that peer as the other lines seem different.

Since your node is online, it may be normal logs about offline nodes that you're trying to connect to (can't tell most of the domain names in the screenshot).
Or if there are far too many and you're exclusively connected to peers with plain IP address, perhaps you have DNS issue where your machine can't resolve those addresses' IP.

Anyways, you can provide more info and better readable screenshot.

Well I kinda suspected the same thing, I thought it was a DNS issue, not until after I reconfigured the system resolver to use Cloudflare DNS, and even Google public DNS, but the WRN log still won’t go away.

Please what infos would you like me to provide?
