NET::ERR_CERT_INVALID

Type “badidea” or “thisisunsafe” directly on same chrome page.

Do this if you REALLY SURE about the link you are trying is safe. In my case I was trying to setup stackstorm locally using vagrant and virtualbox

Chrome version: Version 92.0.4515.131 (Official Build) (x86_64). Source


In Chrome (including version Version 105), browse url:

chrome://flags/#allow-insecure-localhost

allow insecure localhost in chrome settings

Refer to this Stack Overflow for more information.


This works, too:

  1. See "Your connection is not private. blah-bla-blah"...
  2. Type "thisisunsafe" (key listeners pick it up).

1. When you see "Your connection is not private...NET::ERR_CERT_INVALID" warning on Chrome,

2. Just type "thisisunsafe" and wait.


Note: Last time this was tested, Chrome latest version was 104.0.5112.79
