動かなくなった?

$ speedtest-go
Warning: Cannot fetch user information. http://www.speedtest.net/speedtest-config.php is temporarily unavailable.
panic: runtime error: invalid memory address or nil pointer dereference

再インストールで治った?( pkg reinstall では治らなかった )

$ pkg uninstall speedtest-go
$ pkg install speedtest-go

以下のエラーが出ることがある?サイド実行したら動いたのでタイミングの問題?

speedtest-cliを使ったほうがいいかもしれない(公式のSpeedtest.netのspeedtest CLIは動作しなかった)
