Help - Install extension via .VSIX

[moly7x]

Hello, I'm using code-server v3.8.0. This is the first time I'm using it.
I can't install many extensions via .vsix file.
Example like: HTML CSS Support extension

I always get
Corrupt ZIP: end of central directory record signature not found

Evenly I tried install via CLI code-server --install-extension /home/coding/ecmel.vscode-html-css-1.8.1.vsix
But get same result
Corrupt ZIP: end of central directory record signature not found [2021-01-15T18:51:38.376Z] error vscode Failed Installing Extensions: /home/coding/ecmel.vscode-html-css-1.8.1.vsix [2021-01-15T18:51:38.377Z] error vscode Error: Failed Installing Extensions: /home/coding/ecmel.vscode-html-css-1.8.1.vsix at J.installExtensions (/usr/lib/code-server/lib/vscode/out/vs/server/entry.js:540:516) at processTicksAndRejections (internal/process/task_queues.js:97:5) at async J.run (/usr/lib/code-server/lib/vscode/out/vs/server/entry.js:538:205) at async /usr/lib/code-server/lib/vscode/out/vs/server/entry.js:545:678 at async process.<anonymous> (/usr/lib/code-server/lib/vscode/out/vs/server/entry.js:553:912)

:( Can someone help me? My English is not good. I hope I can be helped soon ^^

In the past when I've seen this it's because there was a network error that corrupted the downloaded vsix. Could you try downloading the extension again and see if that resolves the issue? Related issue: #2294
