What is the issue you’re encountering

I can use the Windows SSH client to connect to my remote server, but when I try using MobaXterm I cannot.

What steps have you taken to resolve the issue?

I’ve tried various ways to proxy the connection, including proxying involving the Windows SSH client.

What are the steps to reproduce the issue?

  1. Set up SSH access to a server running cloudflared.
  2. Install the WARP client on a Windows machine.
  3. Verify SSH works for the Windows SSH client.
  4. Attempt to use SSH from MobaXterm to the same destination.

After about a minute of a blank screen, MobaXterm outputs the following:

Remote side sent disconnect message
type 11 (by application):
"cloudflare: origin connection closed"

The remote server shows nothing in packet captures or auth.log while I am waiting.

I’ve confirmed PuTTY works as well. From packet captures on my client machine, it looks like no encrypted data ever occurs when using MobaXterm. There are a bunch of bilateral keepalives, then a server-side reset and disconnect message. From server logs, the connection is hitting the server but I couldn’t tell you what the issue is from either packet captures or server logs.

I wouldn’t know what to look for in either the captures or logs.
