Hi Please,

Check you email accounts settings is correct and is that send test mail is working.

Admin>>Configufation >>EmailAccount

or by this link Admin/EmailAccount/List.

Might be your email server is taking more time to respond.

Generally this error occured due to incorrect information of smtp server or internet connection problem. (+ Firewall)

OK
