Can't upload solution after upgrade to Outsystems 11


So yesterday i upgraded my company's Outsystems Development environment to Outsystems 11.

We have to change de FrontEnd server, because the last one didn't meet the requirements of Outsystems 11, however, i'm trying to upload my old Outsystems 10 solution to this new Outsystems 11 environment and i'm getting the error "The page was not displayed because the request entity is too large." or connection timeout.

Does anyone had this problem and can help me fix it?

Best Regards,

João Cardoso


Hi João,

Yes I’ve seen this problem before. Your solution is too large. You could try to split up your OSP in several pieces.

Or else, see if this post can help you with tips to extend the request timeout and maxAllowedContentLength in IIS:
