Hi @claudio_9251, I'm not too surprised by this. NuGet has deprecated many of it's ODATA( v2) endpoints which has caused some issue within ProGet, we have documented this in our NuGet v2 troubleshooting guide. It is very possible that Telerik (Progress) has not made these changes on their end which may be causing this. This is especially true when it comes to connectors because ProGet will pass through a lot of the V2 queries the client makes to the remote endpoint. Either way, the NuGet v3 API is the proper API to use going forward and we highly suggest using that. Thanks, Dan
