Couple of crashes

2 days ago my dappnode stopped staking. I had to reboot it a couple of times. Then it was staking fine for one day. And again failed…

Sometimes it works back but not all validator are enable. Look likes I had issue with geth. But not sure. I just switched to light client i will see how it goes. I upgraded to lastest geth and prysm ( I dont know why but it was not up to date? Althought auto update is enable).

My internet connection seems rock solid.

Access is done through android, not the easiest to past logs here.

I can upload a 16mb log not sure how usefull it would be. Any input is welcome!

Geth is not the problem. I was staking fine with light eth1.0 client for all night, then today crash again. A couple of reboot later I only get half of my validator running correctly. Openvpn connection doesnt work. I need a hdmi cable coming tomorrow for troubleshoot. Could be a bad nvme?
Worth doing a new fresh install?

Working fine for a couple of hours.
Ipfs disable
Light client
Monitoring package disable
One issue not sure if it is related :
Prysm ui is not fully fonctional and I have a warning message I cant fully copy paste being on a phone :
Http failure response from http://prysm.dappnode/api/v2

Firstly you have the latest version:

  • Geth
  • Prysm
  • DAppmanager

Do you have access to the DAppNode UI or the Prysm UI?

If you have access to the DAppNode UI, it would be great to paste your logs or download them and send them to see what is happening. You can do it if you go to Packages > Prysm > logs.

The Prysm UI error seams something visual, not related to the validator. If you have access you can access the logs from this UI in the Analytics section. Check if you are using some ad blocker, with brave for example you have to disable the shields to navigate well for the UI.
With no logs we can’t know what is happening.

Few versions before there were some error seems this (Validators stopped working after a while) but they were fixed in the last 2 version.

Thanks for your answer
Your right I used different browser and it fixes the prysm ui bug.

Ipfs disable and light client. No crash so far not 1 attestation missed.

Will keep it like that for a week
If it crash again I will copy past.
Here is some error message I managed to save, not sure if its related :

No issue so far with ipfs disable and light client.
Every 2-3 days I miss a handfull of attestation in a row. I check prysm log (beacon and validator) but I cant see anything wrong. How can I troubleshoot that please?

Attesting performance issues is a hard task so I would recommend installing some tooling to facilitate it:

  • Make sure you are running the latest version of Prysm
  • Install the DMS package so you have access to the beacon node + validator Prometheus + Grafana metrics
  • Gather logs around the times you missed attestations (accounting for timezone offsets in the logs)
  • Go to Prysm’s Discord and share you case there. They have the expertise to help in this case.

Small updates. I missed a couple of attestation in a row, then back to normal. I try to reach my dappnode but openvpn connection don’t work. I will keep like that but something is wrong…
