Unable to log in to Bug Reporter

Hi dear developers,


I have a problem when logging in to Bug Reporter.


I have joined the developer program, and I am a registered developer, so I can access iTunes Connect, but when trying to log into Bug Reporter, it says "The account does not exist." But there is no problem when logging in to other services such as Apple Develoepr Forums.


I registered as a developer (not developer program) with another email and Apple ID, and I can access the Bug Reporter from that account, but I can't access Bug Reporter from the first Apple ID which is in developer program.


Is anybody having the same issue? Do you know any solve to this problem? I want to install iOS betas as of WWDC 2016, and I want to submit its bugs to Apple.


The picture of error is available on http://s7.picofile.com/file/8255498618/image.png


Thanks a lot!
