Error 500 with 2.8.1

[bondskin]

Hi,

Last night Watchtower updated my Heimdall instance to 2.8.1

Linuxserver.io version: v2.8.1-ls356

Since then I am getting error 500

Restarting does not help.
Nothing was changed for months by me.

issue fixed, my .env was faulty in regards of APP_KEY and caused the issue
