ISSUE: ZeroTier can't be contacted through TunnlTo/WireSock

[Permanently]

Describe the issue
Whenever connected through TunnlTo, 95% of the time I can't communicate through ZeroTier. I typically get a response of "Connection timeout". Split-tunneling doesn't seem to make a difference, not split-tunneling the subnet. Pinging works, but not connections like SSH.

To Reproduce
Steps to reproduce the behavior:

1. Install ZeroTier and TunnlTo.
2. Join a ZeroTier network, and put some other devices on that same network to test connections.
3. Try establish a connection (e.g., SSH) to another device on the ZeroTier network.
4. Observe.

Expected behavior
I expected to be able to establish connections on my ZeroTier subnet.

Tested on official WireGuard client
Just tested on WireGuard (without kill-switch enabled), and it worked. It also worked when using Mullvad's client.

Tested on different VPN servers
Yes.

Screenshots and GIF's
N/A (unless if "connection timed out" is useful?)

Tunnel Config
Provide a screenshot of your tunnel config with tunnel name, private key, public key, pre-shared key and endpoint removed.

Logs
Here you go. I made a connection to a ZeroTier IP, and it was not listed at all in logs. See here.

Starting WireSock directly
If possible, follow the instructions below and comment on the outcome:

1. Open TunnlTo and Enable the tunnel (this will save the config file to disk)
2. Disable the tunnel and close TunnlTo
3. Open a command prompt and issue the following commands:

cd "C:\Program Files\WireSock VPN Client\bin"

// Ensure you alter the <YOUR USERNAME> component of the path
wiresock-client.exe run -config C:\Users\<YOUR USERNAME>\AppData\Local\TunnlTo\tunnel.conf -log-level all

Same issue. Nothing in logs, and no change in behaviour.

There is the option of setting up zerotier as a client on your VPN server and configuring some routes to negate having to use 2 clients completely.

I've not used Zerotier but I'll have a look over the weekend (if I get a chance to see if I can replicate the issue)

The problem is that is there's an assumption I'm in control of the VPN server. Unfortunately, I'm not.

@Permanently this appears to be an issue at the WireSock level. If it's still a problem I suggest making a thread over on the Wiresock support forums.
