@czonneveld I got a solution from UiPath Support today. Just add the Task UiPath Install Platform as first task in your pipeline. It will install some local tool on the deployment agent so the task is not trying to reach the external url https://www.myget.org/F/uipath-dev/. That caused the timeout for me, because it was blocked by our firewall.
after once using the UiPath install platform task everything works again. Could even disable the task again.
Check this link with the specific part for the UiPath Install Platform task: UiPath Integration - Visual Studio Marketplace
for the future it would be great if such crucial changes are communicated better. It’s an easy to share information, but has huge effects on companies operations. For us this update just crashed the complete uipath release management for half a week.
