I get below kind of errors (URL is not important) when working within company firewall/proxy setting:
212.uuu.xxx.yyy|Mon 03 Sep 2018 10:56:50 +0200|/srv/http/D/|transformation error
212.uuu.xxx.yyy|Mon 03 Sep 2018 11:41:25 +0200|/srv/http/D/|transformation error

Corresponding access.log for 1st record from above:

It is working fine outside of company proxy/firewall with Chromium.

Thanks.

Same error with Hiawatha 10.8.2 and 10.8.1 on Arch Linux.

Looks like there is an XML error in the index.xslt or error.xslt file. By default, those files are in /etc/hiawatha (or wherever your Hiawatha config is located). It's also possible that some site uses a specific file set via ShowIndex or ErrorXSLTfile.

I haven't changed those *.xlst files under /etc/hiawatha in any way. Here are the checksums:
$ /etc/hiawatha: md5sum *.xsl*
ca83c61dad19456743bf9d20afdd9b91 error.xslt
9686c05533bc73417f6122edf2933b2b index.xslt

What is puzzling is that it works with curl, Chromium, etc. outside of company settings.

What is shown if you used 'ShowIndex = xml'? It will show the XML that is used with the stylesheet.

In that case it will show the XML including all the files which are present in that directory.

Could it be that it XML contains any special character that might corrupt the XSLT process?

No, all characters returned are either isprint() or isspace().

I downloaded the output with curl, and checked with
while ((c = getchar()) != EOF)
if (!isspace(c) && !isprint(c)) printf("%02x",c);

As mentioned, problem occurs in company/firewall context in a reproducible way.
