Hi Szymon,

Is MaDDash actually listening on port 8881 after being restarted?

Do you have a single `http:` and a single `serverHost:` section in /etc/maddash/maddash-server/maddash.yaml?  What is their content?

Antoine.

Hi,

That error is because Apache can’t connect to the local maddash-server process. What is in /var/log/maddash/maddash-server.netlogger.log ot  /var/log/maddash-server/maddash-server.out?

Quick update. After restarting httpd and maddash it seems the previous errors have gone. It's just now the single proxy error and the same lack of grids displayed.

All logs after fresh httpd and maddash restart:
