Issue with Setting Up the LanguageTool Plugin

Hi everyone,

Apologies if this has been asked before.

I'm having some trouble with installing the LanguageTool plugin. I followed the installation steps as shown in this video, but when I get to the part where I need to press the "Start Local LT Server" button, no window pops up, unlike in the video.

I have consulted my company's IT department, but they haven't been able to identify the issue.

Additionally, when I press the "Test LT Server" button below, I get the error below. 

Does anyone have any troubleshooting tips or suggestions for resolving this issue? Any help would be greatly appreciated. 

Thanks in advance. 

PS- Trados Studio 2022 SR2 - 17.2.11.19134
       Language Tool - 4.0.5.2022
