Environment Variables: Errors

1

I just updated the firezone container to the lastest version and I’m trying to update the environment variables to reflect thier new values. I’m encountering the following error:

22:10:06.653 erl_level=error domain=cowboy pid=<0.500.0> [error] #PID<0.501.0> running FzHttpWeb.Endpoint (connection #PID<0.500.0>, stream id 1) terminated

These are the two variables/values I’m updating:

PHOENIX_EXTERNAL_TRUSTED_PROXIES=[“173.245.48.0/20”, “103.21.244.0/22”, “103.22.200.0/22”, “103.31.4.0/22”, “141.101.64.0/18”, “108.162.192.0/18”, “190.93.240.0/20”, “188.114.96.0/20”, “197.234.240.0/22”, “198.41.128.0/17”, “162.158.0.0/15”, “104.16.0.0/13”, “104.24.0.0/14”, “172.64.0.0/13”, “131.0.72.0/22”, “192.168.1.253/32”]
PHOENIX_PRIVATE_CLIENTS=[“192.168.0.0/24”]

Any insight would be helpful, hopefully this is caused by bad input on my part.

Thanks for the report @gobijerboa! A fix is in the works

Excellent, thanks for all the good development work. I’ll keep an eye out for a new image to publish.

If you try wrapping the entire variables in single quotes, does the error go away? We parse these as a JSON-encoded string.

Negative, the single quote becomes the unexpected character. I’m using a .env file so technically speaking I don’t believe the variable needs to be quoted.

Errors:
