SMTP has stopped working, password incorrect but it is not

Have had eM Client for 6 months and has been working, now all of a sudden SMTP is not working due to wrong password, but the password is correct and POP3 is working with my credentials.

Hello,

Please turn on in Tools - Setting - Advanced SMTP logs under your account restart eM Client and try to synchronize.

after this send them to: [email protected] together with this URL: https://discourse.emclient.com/emclient/to…

regards
