Difficulty Connecting via SoftEther Dynamic DNS; VPN Azure Works Fine

Hello fellow SoftEther users,
I've encountered a peculiar connection issue with my SoftEther client setup, and I'm looking for some insights or solutions.
Setup:
SoftEther VPN client installed on a Windows PC within LAN A.
SoftEther VPN server set up in a different location, LAN B.
Connection attempts are made using port 443.
Also enabled the "VPN over ICMP / DNS Function" on the server to test, but without success.
SoftEther VPN Client version: 4.34, Build 9745.
Issue:
While in LAN A, when trying to connect using the server's public IP or the SoftEther Dynamic DNS (e.g., exampleDNS.softether.net), my client fails to establish a connection. However, switching to the VPN Azure setting (e.g., exampleDNS.vpnazure.net), results in a successful connection.
Now, when I shift my Windows PC's connection to my iPhone's 4G network, both the VPN Azure and SoftEther Dynamic DNS connection methods work perfectly.
Worth noting: From LAN A, I'm able to successfully ping the public IP address of LAN B, also exampleDNS.softether.net, and exampleDNS.vpnazure.net (which resolves to a different public IP).
This behavior leads me to believe there might be a specific restriction or block in LAN A. Has anyone encountered a similar scenario or has suggestions on potential fixes? Any advice would be deeply appreciated.
Additional Note:
Some may wonder why not continue using the VPN Azure setting if it works. The primary reason is the noticeable difference in performance. The VPN Azure method is significantly slower, and for my day-to-day tasks and requirements, speed is of the essence. I'd very much prefer utilizing the SoftEther Dynamic DNS setting if possible, given its better performance.
Thank you in advance!
