@atripp Thanks so much for the information

Please note that local connectors are fine, public connectors to nuget.org are deleted.

Thanks for replying.
Yes, the connector is no longer in the connectors of the feed. It's totally removed and I can not find any log or job related to the removal.

Whenever we add a public connector (https://api.nuget.org/v3/index.json) to a feed, it works fine for few hours and then it disappears after some time (usually within a day).
I've checked all the Diagnostic Center logs, jobs, event logs and executions but haven’t found any clues so far.
Can anyone help with this issue?
