A request has failed extension error

[OrtooJai]

Summary

When using SLDS Validator, as part of the SFDX VSCode extension pack, it continually fails (about once every minute). This causes the VScode "A request has failed" notification to appear every time.

As far as I can tell the SLDS class validation in LWCs still works despite this.

Unfortunately the "a request has failed" notifications are quite disruptive.

Did you ever get this resolved? I have a similar issue (i.e. My set up is in Windows)
I'd like to know what this issue was. I've already restarted VS Code, the extension. Not sure what else I can do.

[MriteshAdak]

Same question here, I started seeing this error today.
I am on windows but using WSL.

[OrtooJai]

Unfortunately I was not able to resolve it. Instead I disabled the SLDS validator extension and have been developing without it.

The same problem happens to me. I'm using "Microsoft Build of OpenJDK with Hotspot 17.0.10+ 7 x64".
