Gentlemen. I have a problem that the 2013 outlook does not take more than one concession with nethserver 6.9.
Logviewer(DeviceId=E70228B2F34B4285B8A1FDDDB0E112B5&DeviceType=WindowsOutlook15 HTTP/1.1" 502 434 “-” “Outlook/15.0 (15.0.4963.1000; MSI; x86)”)
Logviewer httpd error_log

I’m sorry but Community is primarily English speaking for ease of everyone here.
Can you translate your post in English? Google Translate would be okay
Is there something more at the log? I’ve found some entrys at sophos forum with your error message, but they have always a message with timeout too.
The solution is to increase the HTTP Keep Alive Timeout to 3600.
