Hi,

I have a Gledopto 618WL-4 ESP32 controller. I had this working at home controlling several led strips, and moved it all to a new location with new wifi. I reset the controllers and reconfigured using WLED-AP to connect to the new wi-fi which it did, and when i join that wifi on my phone the WLED app shows the device as connected, however when i click on it the UI wont load it just stays on a black screen.

I am thinking there must be something weird with the new wifi. Ive tried resetting a few times and rescanning the wifi etc but always the same.

I am looking at a new router just for the led setup, am i right that i just need a wifi router and no internet connection?

Thanks
