Login failed error 503.
I don't know if this temporary, due to some upgrade, but the login didn't work for me (with error 503).
In order to login I had to use the ssl-ed version of the site ( https://developer.qt.nokia.com )
I had the same error, help resetting passwords, cashe and cookies.
Try may be it will help you
zes, me too. I have reset my password, then after a while became ok.
503 means, most of the time, that the cache system (varnish) didn't manage to pass the request to the web server (apache). Or that there is a mixup somewhere with cookies, proxies and the browser cache. Clearing your browser should handle it, if not please let us know. The contact us form @ http://developer.qt.nokia.com/contact does not require a login.
