Cryptpad: Is this a bug or must I configure something?

Hey all who have tried cryptpad on NixOS/with nix!

I tried it out today, and neither the nixos module, the module with the pkg from nixos-unstable, nor a manual start with the default config worked. It showed only a 404 error page, containing the cryptpad logo, so fetching this stuff works.

Disabling most of the security stuff and enabling verbose silly logging does not help and also provides no helpful information:

You can configure the administrator email (adminEmail) in your config/config.js file

    #  #  #   ##   #   "# #"m  #   #    #"m  # m"   "   #
    " #"# #  #  #  #mmmm" # #m #   #    # #m # #   mm   #
     ## ##"  #mm#  #   "m #  # #   #    #  # # #    #

Your configuration probably isn't taking advantage of all of CryptPad's security features!
This is acceptable for development, otherwise your users may be at risk.

This is probably not what you want for a production instance!

Running strace cryptpad, the only possibly interesting lines similar to

accept4(18, NULL, NULL, SOCK_CLOEXEC|SOCK_NONBLOCK) = -1 EAGAIN (Resource temporarily unavailable)
…
futex(0x7ffda497e438, FUTEX_WAIT_BITSET_PRIVATE, 0, {tv_sec=17563, tv_nsec=405242000}, FUTEX_BITSET_MATCH_ANY) = -1 EAGAIN (Resource temporarily unavailable)

Does anyone have a suggestion what could be the problem? I didn’t file a bug report immediately, because according to the relevant issues/prs, cryptpad on NixOS was tested. Am I only missing something out?

I that can help, there is a working cryptad configuration using NixOS here: http://cgit.notk.org/asmadeus/nixos-config.git/tree/machines/jormungand

To complete a bit the config is split in these three files:



in config.js the most important things are the domain urls.
in nginx.nix I took a shot at adapting the upstream nginx config example, because as you noticed with a simple reverse proxy (or directly accessing the node.js process port) you’d get a 404 on the index for some reason.

Some of the things don’t work with just a reverse proxy because cryptpad isn’t expecting the data to be split like we do (e.g. it’d like to find some stuff in its /nix/store directory as that’s the home for cryptpad…) and using nginx works around these glitches (definitely bugs, but upstream hasn’t been very reactive to github issues I opened last month so I didn’t report that yet)

Anyway, it works with the proper nginx config so it does work, the module could use some helper to generate the nginx vhost configs though…
