Upgrade from 16.0.8 to 16.0.9 failed

Using the web update feature, after a long wait on the “Downloading” heading, I get an error message :
Parsing response failed. <!DOCTYPE HTML PUBLIC “-//IETF//DTD HTML 2.0//EN”><html><head> <title>504 Gateway Timeout</title> </head><body> <h1>Gateway Timeout</h1> <p>The gateway did not receive a timely response from the upstream server or application.</p> <hr> <address>Apache/2.4.29 (Ubuntu) Server at xxxx.yyyy.com Port 40001</address> </body></html>

I have no idea what is wrong. Would appreciate any suggestions.

Perhaps you can wait a few days and then it works. Minimize CPU-usage and bandwith for other software.

Perhaps you can use the manual upgrade. Not tested.


Thanks for the suggestions. For info, no other apps were running on the server, and there was no network traffic (other than the download).
Will try the manual upgrade.
