Hi,

according to your description the P4-webserver cannot find the file that contains GHL Connect.
You can check the filesystem status on the Communication in GHL Control Center. If it is not checked, you can easily restore it using the internal update page.

Call it using the IP-address like so: http://192.168.1.223/update
Then select the file spiffs.bin from the WiFi-Update-Tool package, which you can download from here: https://www.aquariumcomputer.com/dow...le-esp-update/

This will take 1-5 minutes until the wifi will be automatically restarted. Check the filesystem status again and if it is checked now, use the ip address in your webbrowser to load GHL Connect again.
