Unknown error while opening the connection! For Bounce server

[Ashish Shukla]

Hi,
I want to setup new bounce server but getting error, Unknown error while opening the connection!
While I checked both server, Mailwizz and bounce, have same Php 7.3.26. Not sure what exactly problem. Can you please help?

Did you check the (imap)server logs? The answer should be there...
