Dashticz 4.0.5 not loading

[Chris12]

Hi,

This morning I updated my domoticz to the latest version available (using 2026.3 (build 18335)), and as well updated the dashticz dashboard to the latest 4.0.5 version. Old version was 2025.1 (build 16703), and dashticz 3.14.1.2

Domoticz is running fine, but the dashtizc dashboard is not loading. I get error:

Can't access Domoticz via http://192.168.1.11:8085/
Check domoticz_ip in config.js

For more help, visit the Dashticz documentation.


Via F12 in my Firefox browser I can see the following error:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://192.168.1.11:8085/json.htm?type= ... uth&plan=0. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 200.
Domoticz error code: 0 error!
Please, double check the path to Domoticz in Settings!


My dashticz settings:

config['domoticz_ip'] = 'http://192.168.1.11:8085';
config['enable_websocket'] = 1;
config['use_cors'] = 0;

I played arround with the above websocket and cors settings (enable/disable), but the dashboard page still shows the error (after ctrl+F5)
Any ideas how to further troubleshoot and solve the issue?

In the old version domoticz and dashticz were running fine (except my TADO integration, which needed the latest domoticz, that's why updating)

Have you added you Dashticz IP to the trusted networks in Domoticz?
See some other post on this topic

Hi,

My network is already defined within the trusted networks!

config domoticz:
192.168.1.*;127.0.0.*;172.16.*;172.17.*;172.20.*;10.*

And nothing changed there except adding the IP ranges of the synobridge config (troubleshooting the issue).

I figured out what is the issue!

Allowed CORS Origins field in domoticz was empty (never used that before), added my domoticz IP there and now the dashboard is loading.
Now some troubelshooting to do because some items/graphs are resized.
