I have no idea what the cause would be from these logs and cannot reproduce

[Enes5519]

I'm just opening the VSCode program and it says they are on the output screen.

[Enes5519]

But it's not a problem when I run it myself.

I discovered (in the hard way) I had not installed Composer.

[josemi-ca]

I'm also experiencing this issue.
Was anyone able to fix it? https://stackoverflow.com/questions/56725646/php-language-server-error-on-vscode-connection-to-server-got-closed-server-wil

[yaayes]

I've started to see this in the vscode console after the new update if that could help!
and it's really annoying because at the moment you are writing your code the output box open and the cursor lost focus!

September 2019 (version 1.39)
Update 1.39.1: The update addresses these issues, including a fix for a security vulnerability.

Update 1.39.2: The update addresses these issues.

[PtitPuce]

Same problem here, I'm trying to investigate the best I can, but have no clue where to start.
One thing for sure : XDebug is working fine. It can be started and used properly.

experiencing the same issue on my ubuntu 18.04
also, due to this, the parsing restarts again and again resulting in slowing down the whole system

[charlesdeb]

I have something similar but not identical - so it may not even be related. On start-up, my console output in VSCode is telling me:

[Extension Host] PHP Language Server: DEBUG     Checking PHPLS_ALLOW_XDEBUG
DEBUG     The xdebug extension is not loaded    console.ts:137

[Extension Host] PHP process connected      console.ts:137

This may be normal behaviour.

When I press F5 to start a debugging session, it all appears to work fine, and processing stops at the correct breakpoint. But, I cannot press any buttons in the debug toolbar to continue, step in or step out etc. Keyboard shortcuts don't do anything either. Nothing is logged to the developer tools console or the "problems" area of vscode. The only buttons/commands on the debug toolbar that seem to do anything are ctrl-shift-f5 (restart) and shift-f5 (stop). This used to work fine, but over the last week or two it seems to have stopped. I have tried upgrading to xdebug 2.9 but that didn't make any difference. I think it's a VScode thing. I am using vscode 1.41.0 (although the problem first cropped up in the previous version) and php debug 1.13.0.

If it helps (since this is still an issue in 2021), in my case, running composer update inside the extension folder managed to workaround the issue:

cd .vscode/extensions/felixfbecker.php-intellisense-2.3.14/
composer update

I assume there might be a dependency failing.
