CURL commands 'hang' via tailscale subnet routing

We have a few sites, where left side is AlmaLinux 8 and the right is Windows 10/11

Tailscale is setup for Subnet routing. We use a simple CURL command to pull a static image from an IP enabled camera

Via a regular VPN, it works fine, via Tailscale, it seems to just hang and the process never dies.

/usr/bin/curl -o //tmp/pics/picture.jpg --connect-timeout 5 --retry 2 --anyauth -u admin:XXXX/01 http://192.168.88.139/ISAPI/Streaming/channels/101/picture

This only seems to happen via a Tailscale VPN. Almost like an MTU issue but I am not sure

Would love some assistance
