Newly added codeless events not opening

After adding a new event handler and trying to open it i get the Network Error message
clearing the cache did not help

in case you need it
app id : 07D0CC0C-4A50-198B-FFFB-78866CCD9600

solved
it was an error about the folder name
cant name it “ads”

Hello @mohammad_altoiher

Glad to hear it!
I assume browsers (or its plugins) block requests with any mention about ads
