App store connect operation error while distributing build to app store connect

I'm trying to upload ios app build to app store connect but getting this error, any solution?

I'm getting exactly the same 11 hours after the OP. Never happened before. What's going on?

Could it be the data center is overloaded ? I would try at night or early morning, at a time of lower traffic.
