Hi All of a sudden the server where typesense was installed months (1 year?) ago, returns

ERR_CONNECTION_REFUSED

I already tried to restart the server, run

sudo systemctl start typesense-server.service

, regenerate SSH certificates, checked existence of config file, ... nothing changed The instance is using an NGINX front, so it can show some stuff in the web. This worked like butter for months (1 year?) and suddenly creeped Anyone has an idea what to try next? Direct calls to the api endpoint also fail, same "server does not respond" issue
