I just picked up a RPi 5 and swapped out my RPi 4 that was running Umbrel flawlessly. The Pi 4 had no issues running Bitcoin core, Electrs, Mempoo, Jam and Snowflake. I made sure Bitcoin core was up to date to v27.
As soon as the Pi 5 booted up, both Jam and Snowflake (Tor Relay) would not open, giving an unable to connect message. (It appears Jam has an issue with 1.1 and an issue has been filed).
After troubleshooting for quite some time, including switching ports on the docker container as per some community posts, I resorted to doing a fresh reinstall the Pi 5 image using BalenaEtcher and wiping my 2TB hard drive connected to the Pi. The first thing I did after initialization was install Snowflake and it gave me the same error. I switched the docker ports from 3800 to 3805 and to a number of other ports without luck.
I reinstalled core, electrs, and it’s syncing without issues.
The logs are always the same for Snowflake:
snowflake_app_proxy_1 | Error waiting for port: "The address 'snowflake_web_1' cannot be found"
snowflake_app_proxy_1 | Retrying...
snowflake_app_proxy_1 | Error waiting for port: "The address 'snowflake_web_1' cannot be found"
snowflake_app_proxy_1 | Retrying...
snowflake_app_proxy_1 | Error waiting for port: "The address 'snowflake_web_1' cannot be found"
snowflake_app_proxy_1 | Retrying...
snowflake_app_proxy_1 | Error waiting for port: "The address 'snowflake_web_1' cannot be found"
The app itself does appear to be relaying traffic per the logs, but I believe the snowflake_web_1 is the frontend GUI that allows us to see the connection statuses.
Dialing into the Umbrel (using SSH), I was able to see that web was having issues starting:
$ sudo docker compose ls

Checking the container logs, it also confirms it’s been restarting.

I also filed an issue here directly in Github. If this is incorrect, please feel free to remove.
There are some posts online that help with setting a smaller page size, but I’m not the best with docker. Before I start messing around with the underlying system, does anyone have any ideas on how to fix this properly? Like I said, all my apps including core, eletrs, jam and snowflake worked without any issues on my RPi 4.
Thanks.
