What could be the reason for the error when reading the exchange file?

Question

1C-Bitrix

The site responds in the exchange request with "zip=yes"
But when you try to send the exchange file in zip, it swears that an error occurred on the site's side when reading the exchange file.
When uploading uncompressed xml, everything works, but the exchange takes a very long time. With what it can be connected?

Answer 1

This is due to the fact that the Zip archiver does not work correctly on the server.
