Host not found in upstream "mempool.space" in /etc/nginx/conf.d/nginx-mempool.conf:49

Hi all,
after a reboot I am getting these error messages:

mempool

I am also unable to start the mempool app.

Any suggestions? Thanks! :slight_smile:

Update: I followed these steps from the troubleshooting guide:

One Umbrel App do not start or it can’t be installed

If you have error that a specific Umbrel App do not start or it keeps staying in “installing”, maybe the docker container for that app it wasn’t installed correctly or it hangs.

Step 1 - Enter using SSH into your Umbrel node:

Step 2 - stop Umbrel node with:

cd umbrel

Normal Linux OS use sudo ./scripts/stop
UmbrelOS (RPi) use sudo systemctl stop umbrel-startup

Step 3 - clean / reconfigure the broken container:

sudo rm .env && sudo ./scripts/configure

Step 4 - apply latest Umbrel update (replace the version number with the latest):

sudo ./scripts/update/update --repo getumbrel/umbrel#v0.4.17

Restart your node:

Normal Linux OS use sudo ./scripts/start
UmbrelOS (RPi) use sudo systemctl start umbrel-startup

You can open Umbrel dashboard, but wait until latest blocks are catching up and also electrs is synced. All txs and channels will appear after a while.

I hope the above was the correct way to face my mempool error?

Channels and txs are not showing right now, it has been taking more than an hour now. Will update if anything changes.

Check the bitcoin and lnd logs.
Is the first thing you should check if a node is not starting after a long time.
1h is not too much anyway.
SSH
cd umbrel
docker-compose logs bitcoin (see if is synced 100%)
docker-compose logs lnd (see if the wallet is unlocked and ready to catch up )

you can optional run the debug log from dashboard or command line sudo ./scripts/debug and see where is the error bottleneck.

ONLY after that start doing anything else, when you know what happen.
NEVER start fucking up the node just because you are impatient.

Thanks for your quick reply!!

So I’ll be patient for now and will check if it u fixes in 1-2 hours and get back here. Thank you alot, my dark lord

Check the logs, watch what is doing

The second part worked! It’s back online!

However, I am still seeing errors in the logs:

what have to do mempool with your working node?
Delete mempool app, is broken.
Install it again IF YOU REALLY NEED IT.

I am still trying to understand why RPi users still insist in installing mempool app. Is taking a lot of resources just for consulting a damn tx once in a while.

Its not that I need mempool in particular. I wasn’t aware that it consumes so many resources, I can gladly uninstall it.

However I’m having issues with other apps as well. For instance with lightning terminal:

lightning-terminal

Unfortunately, reinstall doesn’t fit it

I’m getting http errors in lightning shell as well. It seems to be a deeper issue

Looks more connection problems than internal.
Are you also using Pi-hole app?

Yes, I am. You think pi hole blocks those connections?

I might need to add that I’ve just recently installed pi hole and wasn’t facing any problems before. However, I really like the idea of ad blocking for my network.

Ok but then configure it well.
If you do not know what are you doing, then better don’t do it.

Any hints for a working configuration?

uninstall :grin:
magically all will work just fine.

:smile:

So I guess I still need adblock widgets

No, I don’t use any pihole or widgets.
I just use a good DNS provider that blocks the shit.
Also a chromium browser that blocks everything.

Pi-hole is good, but be careful how you configure it and use it.

Would you share which dns you use?
I never did research on that and typically just set it to 8.8.8.8/8.8.4.4 …

Did you tried 9.9.9.9 ?
Ar many more of them. Just change into your PC or even router the DNS
https://duckduckgo.com/?q=ad+block+dns&hps=1&ia=web

Pi-hole is for more advanced stuff, but for just get rid of annoying ads, use a damn good DNS.

Anyways, thanks for your help!
