SnappyMail Proxy (i.e. webmail) issue after upgrade from 2.3 to 2.4.5

Hello all,

Snappymail through proxy was working fine from my initial setup with v2.3. Recently, I upgraded CyberPanel to 2.4.5 and now the same thing is not working. Though, there is no issue with SMTP, IMAP or with any email functionality.

Exact error when click on Login button:

Request failed
Server message: NetworkError when attempting to fetch resource.

Note: Snappymail is working fine if I try through IP Address. The issue is specific to proxy.
