I am currently not able anymore to upload my iOS App Archive to the AppStore via Xcode. App validation succeeded. Last update 2 week ago was without any issues. Now I get following error message hundreds of times while trying to upload the ipa: The following issues occurred while distributing your application: Part #[different numbers] failed to upload. The certificate for this server is invalid. You might be connecting to a server that is pretending to be "store-033.blobstore.apple.com"... The keychain says: Apple Development certificate valid until 03/2023 Apple Distribution certificate valid until 03/2023 Developer ID Certification Authority valid until 02/2027 Apple Worldwide Developer Relations Certification Authority valid until 2/2023 Any suggestions? Thanks in advance!
