empty_response when attempting to load to new firmware

I am missing some incoming calls and I found the article https://helpdesk.snom.com/support/discussions/topics/6000039005


It suggests using the latest maintenance release firmware at http://downloads.snom.com/fw/mru-preview/snom821-8.7.5.44-SIP-r.bin


When I login to my snom 821 admin > Software Update, enter the firmware URL and click 'Load' I get the following error:


The 192.168.0.11 page isn’t working


192.168.0.11 didn’t send any data.

ERR_EMPTY_RESPONSE


I haven't encountered this problem before with previous firmware updates. Please can you advise?

Please turn it off and try a manual FW upgrade.

Thanks Sean, that solution worked for me on a 715 going from 8.7 to 8.9.
