Can't access WebCore dashboard from Smartthings app



I have a WebCore SmartApp installed on my Smartthings for a long time and I always access the WebCore from my browser to create and edit my pistons normaly, and from the last time that I access WebCore, I didn’t made any modifications, but now i´m having a problem.

Today I opened my Smartthings app and choose SmartApps>Webcore to get my WebCore registration code to edit my pistons, but the Smartthings app show a screen with text “Processing” for ever and not enter in webcore settings o register web browser.

There is any problem with Smartthings SmartApps or WebCore ?

Thanks for your attention
