Hi there,

since a few days my mempool app only shows “connecting” anymore.  
I already tried reinstalling the mempool and the Electrs app to no avail.

In the manage app menu Electrs is constantly showing “Starting”.

log: [umbrel-1662563527281-debug.log](https://community.umbrel.com/uploads/short-url/sUAg00Z2dy2sr3wO2ANL9zG7pis.log) (48.0 KB)

Thank you for your help!

Hello @J0nsan!

We’re sorry you’re facing this issue - lets collect some more information together so we can begin finding a resolution.

I reviewed the log file and found the following under the mempool log section:  
mariadb\_1 | 2022-09-07 14:37:00 1110 [Warning] Aborted connection 1110 to db: ‘unconnected’ user: ‘unauthenticated’ host: ‘[BLOCKING INTERNAL IP FOR PRIVACY]’ (This connection closed normally without authentication)

It looks like we are running into a back-end database authentication error. Just to confirm - are any other applications you are running facing this issue?

Thank you,  
Max

Lightning Terminal gives the Error “EHOSTUNREACH” when trying to open it. Pi-hole seems to work fine. I dont have more apps installed currently.

Hey J0nsan,

After some research and digging we found that this may be a bug with Maria DB (the back-end database service).

Check out this GitHub Issue: [https://github.com/photoprism/photoprism/discussions/1966](https://github.com/photoprism/photoprism/discussions/1966)

We recommend running the following

```auto
sudo ~/umbrel/scripts/app restart mempool

```

If this still does not resolve the issue - please feel free to drop us as many logs as possible so we can investigate further by running:

```auto
sudo ~/umbrel/scripts/app compose mempool logs | grep -v 'app_proxy_1\|tor_server_1'

```

Thank you,  
Max

Hey Max,

the first command didn’t seem to fix it.

Here is the output of the second command:

Hey @J0nsan ! It looks like an odd issue,  
I need to ask you a little more details and hopefully, we’ll find a solution together 🤞  
Can you provide a **screenshot** of what your mempool app is showing you on the screen?  
Could you also provide the **electrs** and **bitcoin** logs?

**You can get the electrs logs using :**  
`sudo ~/umbrel/scripts/app compose electrs logs --tail=100`  
**You can get the bitcoin logs using :**  
`tail -n 100 ~/umbrel/app-data/bitcoin/data/bitcoin/debug.log`

As you have issues with Lightning, Mempool & Electrs the problem could come from Electrs, let’s check this first!

Hello,

the mempool app is always switching between “Connecting” and “Offline”

Alright ! bitcoin logs seem normal, electrs seem to work normally although it fails at some point because it didn’t receive a response in time.  
By re-checking your umbrel-debug.log I saw that you have multiple instances of bitcoin and electrs running can you check [this](http://community.umbrel.com/t/electrs-stuck-reading-app-logs-and-identifying-docker-processes/9373/4) topic and tell us here if it worked for you?

I’m sorry to hear that 😕  
We’ll need to go more in-depth into the electrs & mempool logs  
Could you please provide these logs ?  
`sudo ~/umbrel/scripts/app compose electrs logs --tail=100 electrs`  
`sudo ~/umbrel/scripts/app compose electrs logs --tail=100 app`  
`sudo ~/umbrel/scripts/app compose mempool logs --tail=100 api`  
It should give us more details about what’s causing the **electrs\_app\_1** to crash

Hey @J0nsan! Sorry for the delay,  
That’s weird; It looks like there’s something causing connection issues between apps. Have you modified your **bitcoin.conf** file?

Hello, I am having the exact same problem. It happened just after latest version upgrade. It seems from logs like it is not connecting to db backend; although all modules comes up with no problem when you restart node and/or module.

None of the proposed solutions in this thread worked for me. On the web interface there is a sign that reads “indexing in progress” forever, but seems unrelated to the issue. It has been like this for the past two weeks at least, since upgrade.

Hey @jhava! Sorry to hear that 😕  
Maybe bitcoin or electrs is still indexing data.  
But let’s check the logs to know which one is indexing/causing the issue!  
**You can get the electrs logs using:**  
`sudo ~/umbrel/scripts/app compose electrs logs --tail=100`  
**You can get the bitcoin logs using:**  
`tail -n 100 ~/umbrel/app-data/bitcoin/data/bitcoin/debug.log`
