Description
Type: Bug
Since version 1.100, I can no longer login to HPC clusters like the TACC ones directly in VS Code. I started to notice this issue around June. This week, the updated feedback I received is "Unfortunately there aren't any changes that can be made on TACC's side to
address the compatibility issues VSCode introduced in their latest releases.
They'd have to release a version that corrects those problems. Until then,
rolling back the version will be the only solution."
Extension version: 0.120.0
VS Code version: Code 1.106.0 (ac4cbdf48759c7d8c3eb91ffe6bb04316e263c57, 2025-11-11T16:02:25.943Z)
OS version: Darwin arm64 25.1.0
Modes:
Remote OS version: Linux x64 6.1.0-40-cloud-amd64

Research direction
Start by reproducing the SSH connection failure with VS Code 1.106.0, Remote-SSH extension 0.120.0, and the listed Linux remote environment, then compare it with a rolled-back version. The issue is done when login to TACC or another HPC cluster works in the current release without changes on the cluster side.
