emails stopped working

user_638391490773118

I had an existing setup with email notifications working via my gmail account. I added another camera and set up another app password from gmail but could not get it working, the original camera was still sending e-mails fine. I thought it might be that the software did not like 2 app passwords, so deleted them both on google and made a new one, when i added this new app password to what was the working camera it now does not send e-mail, nothing else was changed. what is going on, it should not be this difficult to get important security devices working properly, any insights appreciated
