Hey,
I'm currently getting the 3001 error passed the character selection.
Things I've tried:
1. --server nasomi.com --hairpin to ashita commandline. I had the double cmdline text entry bug, so --user and --pass are also on there
2. Router reset. Disabled firewall. Completely uninstalled and reinstalled network adapter drivers. "Network Reset", whatever that does.
3. Deleted USER folder
4. Completely reinstalled the client.
I'm on Win10 Pro 1803, build 17134.165

This only happens on this one computer. I have a laptop on the same network that works, so I don't think its ISP related...

Any help would be appreciated, thanks!

After talking with the NasChat guys a bit, I made an alt account and that one seems to be able to connect no problem. Not sure what's so special about the regular one :/
