Login -out after update own extension

I logged in, went to "my extensions" - wanted to update one of my ext, by clicking on "upload" I was logged out and now i can't login again.

If i try to login now:

Console error: "loading rsa stuff (index):361 GET https://extensions.typo3.org/my-extensions/typo3/sysext/rsaauth/Resources/Public/JavaScript/RsaEncryptionWithLib.min.js"

The menu changes to the menu as if I logged in, but i'm not logged in! The icon of the login is loading forever. If i click on a menu link - page reloads and the menu is again as if I were never logged in.
