Cert issue during new install of Brewblox

Troubleshooting
1

I seem to be getting a certificate issue when installing Brewblox software. This happens on a new install of the software on a Pi3b+ with a new SD card and fresh install of the OS.

Setup completes without any issues but I am not able to reach the Web UI using the ```
brewblox-ctl up command.

I’ve tried three times now with a fresh format of the SD card between tries and can repro this same error.

Your help is very much appreciated!

Hardware:
Pi 3B+
New SD card
Raspbian lite 32bit
Spark v1

Firmware and software are up to date - brewblox-ctl update used to check

The issue seems to be with Traefik -

It sounds like the generated cert is having issues.
You can check them by running:

(Do not post the output!)

cat traefik/brewblox.crt
sudo cat traefik/brewblox.key

The crt file should start with

-----BEGIN CERTIFICATE-----

and end with

-----END CERTIFICATE-----

The same for the brewblox.key file, but then with “PRIVATE KEY” instead of “CERTIFICATE”.
The middle for both files should be a square block of gibberish.

Thanks for the quick reply. I have re done the install on another pi and all has gone through now. Thanks again and looking forward to playing with this new code.
