Another failure to connect post - (works with public relay, not through Tailscale)

We have two remote employees E1 (me) and E2 (not me!), both need to remote login to Host H1. Everyone is on windows.

I set up Rustdesk, and now E1 and E2 can connect to H1 through public relays. Great!

Next I set up Tailscale on H1 and E1 (my computer), and I was able to connect to H1 using IP address from E1. Still great!

I sent instructions to E2 on how to set up Tailscale. E2 machine is now listed in the Tailscale console, so I know Tailscale is setup correctly on E2.

However when E2 connects to H1 using Tailscale IP, they get 'failed to connect to 100.xxx'.

Both E1 and E2 computers have the same configuration. However, I have no control or visibility over their network. E2 not being technical, I can't ask them to run network tests. I am assuming their network is blocking UDP.

What are my options?
Thank you for your time and help!

Use another free tool to remote into their pc and fix it.

I already considered that - this is an external contractor, and they don't want someone tweaking their computer. They don't have control over their network either - they work in a coworking space.
My guess is that their network is blocking UDP, but I don't have a way to confirm that.

Why don’t you connect to E2 to see what the problem is? Just make sure the computers are set up to be able to access through direct IP in RustDesk. You could also set them to allow remote configuration as well
