Background: We have an azure DevOps pipeline that we use to automatically deploy a webapp we maintain to an azure test instance.
This suddenly stopped running today with the following error.
TF24668: The following team project collection is stopped: ***********. Start the collection and then try again. Administrator Reason: abuse
where *********** is our project name.
It fails instantly when this happens. It doesn't appear to do anything else other than throw this error.
The developer who initially got the pipeline set up is no longer with the company.
I've looked through the DevOps interface, and I can't find what it means by this "project collection", and I can't find out how to start it.
Any ideas where I should look?
