So I’ve got a Pi 3 and Pi 4 4gb running and I’m running into the problem that I’ve already had to reimage the Pi 4 three times. After about 12/134 hours I can no longer access the Pi through the the IP Address or the foldcovid link. I’ve already switched to a different SD card. Could this be a cooling issue? (Don’t have a fan or heatsink installed.) ---

The web service is unstable. Don’t reimage the microSD. Pull the cord and connect again to recover the access again and check if everything is working again. ---

Cooling is one possibility, another is the power supply. Are you using the official Pi power supply? ---

I am using the official power supply. But this morning I had to reset it again. Noticed that the jobs done are set to 0. Does that get reset every time you reset the pi or have I really not completed a single job? ---

Hello! I have 2 Raspberry PI units: 1 Raspberry PI3 1 Raspberry PI4 8GB I did the download and image process in the microSD card for the 2 devices with the images and instructions of the website: > **[Fold for Covid - Donate spare compute capacity for COVID-19 research](https://foldforcovid.io/#get-started)** > > Fold for Covid lets anyone join the fight against COVID-19 with their spare PCs, laptops, or single-board devices.

The router clients table displays the Raspberry PI3 (foldforcovid) but not the Raspberry PI4. I changed to Ethernet cable for the Raspberry PI4 with no results again. Any ideas? Thanks! ---

We had another issue with RPi 4 the 8GB version - [https://github.com/balena-os/balena-raspberrypi/issues/524](https://github.com/balena-os/balena-raspberrypi/issues/524). Could be related. Can you please download a `dev` image version? It is available on the same dashboard page for download, but there is a checkbox for it. Afterwards you can do a `balena scan` from your computer and see whether it is shown in the list with found balena devices on the network.
