TYPO3 Core

In my version, the tab is active.
But when uploading the extension, there is a soap error:

SoapClient::SoapClient() [soapclient.soapclient]: 'uri' option is required in nonWSDL mode

Backtrace:

I'm also having the same problem using version 4.5.10. The upload tab is active and after starting the upload it fails with the same error message. So I can't upload extension updates at the moment.
