Moved freescout to another domain

Please be aware that these issues will be closed if inactive for more then 14 days :) I moved freescout to a new domain, the steps I did are:

migrated the database and imported the database on the new server.
Downloaded a fresh installation and uploaded it on the server
Followed the freescout/install procedure and it was installed without any error
Can login on /freescout without any problem

Issue I am facing is with fetching e-mails and I keep getting the error:

Error: imap_open(): Couldn't open stream {207.180.219.149:993/imap/tls}. [CLOSED] IMAP connection broken (server response); File: /home/domain/public_html/freescout/overrides/webklex/laravel-imap/src/IMAP/Client.php (230)

I tried disabling / enabled Validate Certificate
tried changing Encryption to TLS / SSL / None

Any ideas what I can try?

Webklex / laravel-imap
