Apologies for the late reply, I had put the extension in 1.47 and completly forgot about it
Issue is still present in 1.49
On my side we are just connecting to our server as it's on the same network and opening the project from there never had any issues before
Here's the result of my output PHP Language Server :
[Info - 5:00:37 PM] PHP Language Server Started (PID: 28468)
[Info - 5:00:37 PM] Indexing 10.16.19.25/docker-data/dev_php8_1/dev/spa-avenue/hadrien (*.php; *.phtml; *.module; *.inc; *.theme)
Let me know if I can provide you with anything else
