could not connect to specific host from Linux server

I have a Linux server and am trying to connect to a specific host, such as 'imap.ionos.com,' on a 993 port. I am using the php-imap package. But receiving a connection timeout error To debug this more I tried to connect to the same host and port with telnet but could not connect. further debugging I could confirm that the error is with the OpenSSL.

here is the exact error.

stream_socket_client(): Unable to connect to ssl://imap.ionos.com:993 (Connection timed out)

I am facing this same error while connecting via SMTP too.I am sure its not something related to IMAP or its package.

What's more frustrating is same code is working on staging and the local server. My first assumption was that IP had been blocked. I have assigned a different IP to the server and still no luck. I also checked the outbound firewall for any network restrictions.

OpenSSL is on the 3.0.1 version If that's a matter thanks.

Have you gone over the various log files, I suggest clear them first so you don't have too many lines to search through.
