Jainish1367 The error that you are seeing there is with the Google MCM portal which is outside of Ezoic. Please can you check that you are on the most updated version of chrome, switch off any ad blockers, clear your device cache and cookies and the re-try.
For checking the email addresses you can see the email address that you have signed up to Ezoic with in the Ezoic dashboard and then cross check this with the email address that Google has sent that email to you on. If they match please let us know and we can go from there. many thanks
