Research direction
Start with the S3 dataset construction in ParquetFileToArrowReader.java and the FileSystemDatasetFactory stack frames, then review how the Java API resolves the bucket region and reports AWS network errors. Reproduce the failure with the reported credentials and determine the required configuration; done means the S3 files can be read without the NETWORK_CONNECTION error.
