[Remote-SSH Bug]: VS Code Server initialization hangs on creating forwarded ports #8942
Comments
|
The workaround I'm using right now is to revert to version 0.102.0. Everything works fine in that version. In versions 0.105.0 through 0.106.1, the forwarded port opens, but seems unable to actually carry traffic. It's very strange. Almost as though it carries the first few packets and then falls over. |

The same issue. |
|
I am experiencing the same issue after updating to the latest version. |

+1 same issue |
|
Same on macOS. |

+1, can confirm the same issue on a Mac M2. Rolling back to Remote - SSH v0.105.1 solved it for me. |

Try disabling the |
|
It seems that switching to the pre-release v0.107.2023090815 build also seems to fix this. |
|
How to install pre-release v0.107.2023090815 build on mac? thanks |
|
0.106.3 was just released with the fix |
|
@roblourens from this log, it looks like the first connection was made using a traditional connection and the followup resolutions (after default package.json configs were applied, perhaps?) tried to resolve using the exec server, which caused things to fall apart. I think this was solely an artifact of the now-fixed default config value application, and so this can be considered fixed. What do you think? |
|
OP here - I just confirmed that 0.106.3 contains a fix (whatever it was). It's back to working. I'd consider this issue closed. |
Is there an existing issue for this bug?

Expected Behavior
On launching my existing remote workspace, the VS Code Server would initialize and I would be able to use VS Code normally.
Instead, the VS Code Server initialization routine never got past the creating forwarded ports step. This threw it into a repeated cycle of needing to reconnect to the server, which caused the same issue to happen over and over.
