Cannot use my Gmail account after changing password

Hi there. In short, I already had 3 Gmail one it and it was working till I changed the password for 2 of them. for the first one, the new browser tab to authenticate and give permission opened up, I confirmed and it reconnected. For the second one, After I click the “Open EmClient” button on my browser, after 10 seconds, it leads to and EmClient still showing the prompt that says the operation may take a while. I tried it many times. Also removed the account and tried to login again, but the same problem appears. what I found out, is that although I grant the permission, I don’t see anything related to EmClient on my Goggle Account permissions page. Please help.

Ok, I have retried it like 30 times until right now. And the last try just worked.
