Tailscale using relay service,slow connection
I travel frequently and use my Synology NAS and Ugreen NAS as a Tailscale exit node. Recently, my connection speeds have dropped significantly, sometimes down to 1 Mbps when using Tailscale outside of my home country , seemingly because the connection is routing through a relay server.
Two months ago my ISP resolved a connection issue. Since then, I get 700+ Mbps while paying for 120 Mbps and all websites that are blocked in my country are now accessible without a VPN and coincidentally I am having this issue with my Tailscale connection speed.
Any advice on how to resolve this or force a direct connection? I do not want to change ISP because options in my area is limited.
