No connection to the server?

I recently bought a new cell phone and wanted to set up my email account there straight away

Although I entered everything correctly, no connection to the server could be established.

It was not a problem on my old cell phone and on my laptop

Can someone help me?

The IMAP as well as the SMTP server must be selected with the appropriate ports and security.

What are you using, TSL / SSL, StartTLS?

I have the server IMAP and I use TLS / SSL. I entered aes and still no connection came, despite Wi-Fi
