Hi @NameRequired, I don’t think there’s much you can do apart from reporting this as a false positive through the respective form unfortunately:

I had the same problem, iirc it took them around two days to sort out.
My best guess is that some algorithm assumes we were trying to imitate the login form of another public n8n instances or something. At least the warning didn’t come back for me since I reported my own instance as a false positive.
