Thank you @RomanNikitenko for the great investigation! Considering that, after fixing https://github.com/eclipse/che/issues/21400, the steps to reproduce this issue are not typical for the Che user (closing the current VS Code Workspace), I believe it makes little sense to continue investing in a fix for this issue. I’m decreasing the issue’s priority to P2. We can come back to it once there will be a real use case when the issue is relevant.

I was able to reproduce the problem only for not secure connections (a certificate was not provided or is invalid):

Another condition to reproduce the issue - Open Folder command usage.

So, two things are required to face with issue:

• valid certificate is not provided
• use Open Folder command

The issue was detected at starting IDE step for not secure connections as starting Che-Code had 2 steps:

• loading the IDE
• open a project using Open Folder command by API.

See Che-Code loading twice at workspace startup for more details.

The issue is not actual for starting IDE after merging https://github.com/che-incubator/che-code/pull/131 as Open Folder command is not used anymore to open a project. But a user still might face the issue:

• for not secure connection
• close a current project and use Open Folder command to open another project/folder
