Failure to Copy to System Clipboard in tmux in Specific Directory

[tqwewe]

Summary

While operating in the $HOME/dev directory (including its subdirectories) and using the yank command Space + y to copy text to the system clipboard, the operation fails to execute as expected. However, when I navigate up to the $HOME directory, the same operation functions as expected.

This issue seems to be specifically tied to operating in an SSH session from a Mac into a PC. Using a terminal directly from the PC does not reproduce the issue; all clipboard functions work correctly in that scenario.

Reproduction Steps

Steps to Reproduce:

1. SSH into the PC from a Mac.
2. Launch tmux and navigate to $HOME/dev directory (or any subdirectory).
3. Attempt to yank text to system clipboard using Space + y.

Expected Behavior:

The yanked text should be copied to the system clipboard, regardless of the current directory.

Actual Behavior:

No visible error upon pressing the keyboard shortcut, but an error message appears when running the :clipboard-yank command:

Couldn't set the system clipboard content: clipboard provider tmux failed

Same issue for me however seems to be present in any directory. My setup looks like WSL2 -> SSH -> Tmux -> Helix. Clipboard works fine from Tmux but not within Helix.

Having this issue, but it's very erratic, sometimes it works, sometimes it doesn't.

Similar issue, Space + p does not work.

To fix Space + y not working, I did the following:
In iterm2, enabling Applications in terminal may access clipboard in General > Selection source

As a crude fix for the clipboard paste I set the following keymaps:

[keys.normal.space]
P = ":insert-output tmux send-keys i; pbpaste; tmux send-keys Escape"
p = ":insert-output tmux send-keys a; pbpaste; tmux send-keys Escape"
