Hey there! How were you able to type this message? Was this performed by signing into your PSN credentials or Steam? Does it give you the error only on the browser I assume? If so, you may want to use a different browser, clear browser cache/cookies, or open up a private window. The other two suggestions to resolve this error is due to you not having any Destiny information on your Steam account. The last suggestion to resolve this error is by deleting your Steam icon and/or changing your Steam nickname.
