Openhab extension fails to initialize for workspace wtih UNC path

[Laffs2k5]

Expected Behavior

Opening a vscode workspace with UNC path in the folders sections and Openhab extension installed should not result in initialize error of the Openhab vscode extension.

Current Behavior

During initialization these two dialog appears:

The output from the extension

openHAB vscode extension has been activated
[Error - 6:29:44 PM] Server initialization failed.

Possible Solution

Current workaround is to have only local paths in the workspace.

Example of working workspace configuration

{
	"folders": [
		{
			"path": "."
		},
		{
			"path": "C:\\Users\\"
		}
	],
	"settings": {
		"files.eol": "\n",
		"files.associations": {
			"**/sites-enabled/*.*": "NGINX",
			"*.config": "properties",
			"*.map": "properties",
			"*.old": "openhab"
		},
		"openhab.useRestApi": false
	}
}

Steps to Reproduce (for Bugs)

1. Create a workspace containing UNC paths.
2. Save as workspace file.
3. Re-open the workspace and observe the error.

Example of failing workspace configuration

{
	"folders": [
		{
			"path": "."
		},
		{
			"path": "\\\\docker1.leiflan\\opt_openhab\\2.5.9"
		},
		{
			"path": "\\\\docker1.leiflan\\opt_openhab\\3.x"
		}
	],
	"settings": {
		"files.eol": "\n",
		"files.associations": {
			"**/sites-enabled/*.*": "NGINX",
			"*.config": "properties",
			"*.map": "properties",
			"*.old": "openhab"
		},
		"openhab.useRestApi": false
	}
}

Context

Accidently discovered this while opening a previous workspace after upgrading both my Openhab isntance and the vscode extension.

Your Environment

• Windows 10
• vscode 1.56
• openhab extension v1.0.0

This is a similar topic to #184, #145 and #112. There is (still) no solution available besides the known workaround.
