Error on initial visit

[johanohly]

I got Maybe running via the docker guide, but visiting the homepage yields a generic error message:

The logs reveal this error message:

From within the container, can you consume /dev/urandom normally?

Try something like:

tr -dc A-Za-z0-9 </dev/urandom | head -c 13; echo

Yes, that seems to run without an issue. I am running Maybe on a synology NAS, which does run a pretty limited version of Linux, but I've only encountered a straight up incompatibility with one other container (it was the cocalc docker image, but 30+ run without issue).

[johanohly]

I think I may have found a similar case in another Ruby project being run on a Synology.

I have the same issue.
