Good morning. New Umbrel Home installation experiencing continuing network disconnection issues, every few hours, requiring a hard reboot to get back up.
I performed a factory reset and even with no apps installed, the problem persisted. I have a static IP allocated to the Umbrel.
I have searched and see many others with the same issue but I don’t see a solution - does anyone know of a fix?
I’m getting no res[onse from Umbrel support and would appreciate some assistance - thank you.
You are right a lot of people have been having this issue and so have I. Mine seems pretty consistent to stop at exactly 8 hours after boot.
On yesterday’s failure, I was finally able to capture the system logs.
I think I traced my problem with the Mender Client. This morning I ran the following command:
sudo apt-get --reinstall install mender-client
My Umbrel has been running for 14 hours now. 
Thank you RodB, I will give that a try…. I’m new here - is “umbrel support” really non-existent? Pretty disappointing experience so far.
I am now at 26 hours and counting!!! 
Still have !!!
Any luck with yours?
Up for 12 hours so far after running the command you suggested - I’ll keep you updated!
I had another crash at about 25 hours running … analyzing my logs … it was having problems with the WiFI … I am on Ethernet and not using WiFi so, I have now permanently disable the WiFi in the OS:
sudo nmcli radio wifi off
sudo systemctl stop wpa_supplicant && sudo systemctl disable wpa_supplicant
There was also some errors saying that I ran out of memory. I have 32GB of RAM and I have never seen it go over 50% Used but I will keep on eye on that when I get up-to 24 hours running again!
ah crap…. thanks for the update. I’m at 27 hours now which is a new record so crossing my fingers.
Ugh … another Memory Failure this morning while I was working with it!
Jan 19 03:55:11 umbrel systemd-journald[415]: Under memory pressure, flushing caches.

At least I have now tracked it down to the container that is causing the issue and consuming too much memory. I am just trying to do too many things at once even with 32GB of RAM on the system.
I stopped the container that was causing me issues and will see if my 24+ hour tests of running without failure holds up.
Glad to hear you are 27+ hours now on yours! Keep me informed, please.
Hi Rod - sorry to hear you’re still having issues. I’ve been up for nearly 48 hours now without any glitches - I’m just running knots and electrs.
Spoke too soon - lost network connection again @48 hours
Are you able to capture the system logs and determine what caused it?
I’m back at 10 hours now … our city had a power outage yesterday so, I shut everything down cleanly during the outage.
My free memory is looking good, so far,
I got some errors related to mender - but this was after I restarted - does that help? I’m far from an expert on all this as you m ay have gathered!
The way I look …
Settings → Troubleshoot → umbrelOS → Download umbrelOS logs
Open the log file that was downloaded and go to the very bottom of the file.
Search for – Boot (backwards)
The data right above this line is what got written to the log file before it completely logged up.
In my case below, I ran out of Memory:
Also, here is my script to clear the system logs completely out and start fresh:
umbrel@umbrel:/usr/local/bin$ cat cleanlogs.sh
#!/bin/bash
sudo systemctl stop docker.service
sleep 2
sudo systemctl stop docker.socket
sleep 2
sudo systemctl stop systemd-journald
sleep 2
sudo systemctl start systemd-journald
sleep 2
sudo journalctl --rotate
sudo journalctl --vacuum-time=1s
sudo reboot
