Hello. The website clock can stop because of all kinds of reasons. Now, if you have a receipt date for your application, you don't need confirmation from the website to know that 150 days have passed since you applied. You don't need to call anybody, to call USCIS, to post on here, to know that 150 days have passed. So, please submit your EAD application, do not call anybody, do not try to fix the clock, etc. Why are you asking, talking to people, etc, when you already know that 150 days have passed?
When you can see that the sun is up, why are you asking for confirmation?
