ESET update error: File not changed within the given time interval

[Lockbits 10]

Hello,

We've a customer whose VP had experienced this error:

Later the problem resolved and product is updating again however he wants to know why this message can appear. It's difficult to get an ESET Log Collector and we tried from ESMC and it give us error when trying to get the log from ESMC server.

Thank you.

This appears to be a problem of a particular proxy server which responds with 304 Not modified even to non-conditional requests which is not in concordance with RFC.
