language server(gopls) not working

[1yefuwang1]

After setting go.useLanguageServer to true, this plugin basically stops working: no auto-completion, no go-to-definition, no quick-info-on-hover.
When I try to restart the language server, the following message shows up.

Detailed info of my vscode:

seems like the same issue as #2767

got the same issue, after upgrading vscode-go to 0.11.5, gopls daemon does not start when vscode started... while rolling back to 0.11.4, all works fine...

I also encountered the same problem, unable to pull up the gopls version at 0.11.5, 0.11.4 is normal

Thanks for reporting everyone

Can one of you check the logs and share any errors that you see there?

• Run the command Developer: Toggle Developer Tools.
• Share any errors from here related to the go extension.
• If there is too much noise here, then reload the window, and you should be able to see errors if nay

Another place to check is the logs from the Extension Host

• Select Output from the View menu
• In the output panel that opens, select Log (extension host) from the drop down on the top right corner.

@stamblerre has found a potential reason for the language server to not load and has a fix for that. Please give that a try as well via the latest beta version of this extension

gopls daemon not started after timeout 😢

Log from Developer tools for version 0.11.6.beta-1:

[Extension Host] Unable to determine latest gopls version: Error: connect ETIMEDOUT 172.217.24.17:443

gopls daemon started after timeout occurred, and all works fine now 😄...

VSCode remote-container with go-extension 0.11.5 and gopls v0.1.7 does not work too. And after switching to 0.11.4 it works again, however it noticed me to rebuild go tools for go version has changed, but I'm using the same go in the same container.

I have the same problem.
I tried ps aux | grep gopls to see if gopls was started and i found the gopls wasn't started at all.... I also tried to restart the language server and got "go.languageserver not found" too.

this is my settings.json for vscode-go
"go.useLanguageServer": true, "go.alternateTools": { "go-langserver": "gopls", }, "go.languageServerExperimentalFeatures": { "format": true, "autoComplete": true }, "go.languageServerFlags": ["-rpc.trace"],

version of vscode: 1.38.1
versiion of vscode-go: 0.11.5
version of gopls is golang.org/x/tools/gopls@v0.1.7 ( I also tried v0.1.3 and failed too )
OS: Deepin 15.11 x86_64

Thanks for your solution!
I uninstalled 0.11.5 and installed 0.11.4 and the gopls could work!!!

@enix223, @kidlj, @js00070,
Can you try the latest beta version and see if that helps?

0.11.6-beta.1 works perfectly! Thanks!

Hello all,

I have just released an update(0.11.6) where we have replaced the outgoing call with known hard-coded value of the latest version for gopls. This should fix the problem reported here.

I have logged an issue #2776 to discuss next steps on how to make this check better, please feel free to provide your thoughts there.
