failed to fetch when i save a change

[pinale]

On a fresh new project, create a teble, save it, ok done.

when i try to modify a table with chrome (adding a field) and press "save"
i got "failed to fetch" and in console (F12)

GET https://api.supabase.com/v1/projects/kmisqvziodlbaehoyedd/custom-hostname
404 bad request
{
"message": "Project xxxxxxxxxxxxx is not allowed to set up custom domain; please contact Supabase support."
}

obviously i've no custom domain on the free tier

the problem occours only in chrome (tried with edge and works).
On Chrome i've clean all internet temporal files, clean all local storage type(local/session/Indeddb/cookies... storage) in the "F12->Application tab"

I would hard refresh your browser. Try a different browser. Restart the instance (if you can).
Then contact support like it says.

the problem occours only with chrome and i've clean all possible.
What about "Restart instance"? i'm using the supabase free cloud service (it's not running local) is it possible to restart? how?

Please check for an extension in Chrome involving CORS. There is one that blocks PATCH commands.

You can restart the instance in the infrastructure settings but if it works from another browser that would not have impact.

as you suggested, the guilty was the extension.
Thanks 💯
