On Public WiFi but not able to connect to via Tailscale app

Tailscale version: iOS 1.32.2
Your operating system & version: iPad IOS 16.1.1

Note that I am unable to connect via tailscale to my home based Synology NAS. I have tested it via other external connections successfully (at my parents home) but public WiFi at work is not connecting. I have event tried to login via login.tailscale.com but no success. All other websites are working though.

Is tailscale being blocked on this public wifi access point. Any thoughts on what the issue might be and if there is a workaround?
