HTTrack Website Copier – Troubleshooting gzip Errors

HTTrack is a free, open-source offline browser utility. Download sites for offline viewing: httrack.com

Issue:
HTTrack sometimes fails to decompress (unzip) downloaded pages on jankoweb, resulting in corrupted binary output instead of HTML.

Observed error:

Error when decompressing
while fetching pages that appear to be gzip-compressed.

Workaround:
In HTTrack, go to:
Set Options → Spider → Force HTTP/1.0

Why?
Forcing HTTP/1.0 disables some server-side compression/transfer behaviors that may trigger decompression failures in HTTrack.

Status:
Testing whether HTTP/1.0 prevents broken gzip responses from the server.
