JSONRPC code 32099 denotes an implementation-defined server error, but I don't think gopls actually ever returns this code. (See gopls/internal/jsonrpc2/wire.go for the ones that it does use.) In any case, if the client failed to connect to the server due to EPIPE, it suggests that the server process crashed.

Did this problem happen more than once? Is it reproducible? If so, next time it happens, could you please share the log you see in the gopls output channel and tell us when you observed this popup (e.g. I was updating gopls, I just opened the vscode, I did refactoring, ...)?

Thanks.
