My environment: vscode 1.96.4 (windows), php debug 1.35.0, Ubuntu 20.04.3 lts, docker 20.10.25, php 7.4.30, xdebug 3.1.5

After months of working properly VSCode PHP Debug extension stopped working. My typical configuration is debugging some php + apache containers on remote host, via ssh.

Looking into extension host(remote) output I can see:

I tried:

• restart docker service
• restart docker host
• rebuild containers
• another container configuration: another subnet, ports
• try another vscode windows host
• reinstall vscode on my dev pc
• remove ~/.vscode-server on docker host

Please give me any suggestions how to fix it.
