Description

Sometimes I got error Uncaught (in promise) Error: Looks like the language server is talking to long to respond, prease try again in sometime.
I'm not sure whether it is reproductive on all environment. It is just for information.

Reproduction Steps

Creates workspace with Che-in-Che.
Starts it.

OS and version:

6.18.0-SNAPSHOT (with some my patches)
Azure AKS (B2s instance)

Diagnostics:

@monaka can this be a random networking issue? Does it happen to any particular language server?

[monaka]

@eivantsov My browser doesn't communicate with any language servers directly if my understanding is sure. So I guess it is not caused by unstable WAN network. And I believe the network in Azure is enough stable.

@monaka nit directly to LS but via a workspace agent (websocket though).

In any case, i'd recommend trying a Che 7 workspace with TypeScript and Java language plugins onboard

This may fixed after I changed my ingress to Traefik (refs #12645).
I close it for now. (might re-open if I could reproduce it.)

@eivantsov I agree Che 7 is the better choice for the future.
But I'm blocked by #12585 on GWT-IDE and waiting to be implemented GIt related features on Theia. :-)
