404 page not found

[tarkhil]

After copying the working setup of alertmanager-bot, I receive 404 error on any request.

/usr/local/bin/alertmanager-bot --telegram.admin=264417926 --store=bolt --template.paths=/var/db/alertmanager-bot/templates/default.tmpl --telegram.token=(token) --bolt.path=/var/db/alertmanager-bot/bot.db --listen.addr=127.0.0.1:8080 --log.level=debug

even does not yield debug messages.

Yes, I've tried to stop the bot, and than connection to 127.0.0.1:8080 gets refused.
