N8N SMTP failue

I want to setup SMTP to recover email. The strange thing is that when I input the email what is registered to user the error occur. If I ad random email there is no email, but of course also email not received.

docker-compose.yml:
smtp
- N8N_EMAIL_MODE=smtp
- N8N_SMTP_HOST=smtp.zoho.eu
- N8N_SMTP_PORT=465
- [email protected]
- N8N_SMTP_PASS=“^!%123!nv5”
- N8N_TRUST_PROXY=true
- [email protected]
- N8N_SMTP_SSL=true
- N8N_LOG_LEVEL=debug

docker log:

Thanks in advance the support.

Please verify if it is the app password and if the ‘login mail’ and ‘sender mail’ are the same.
