upstream timed out about selfoss

You will need to increase the timeout of your web server. It will depend on your web server. For example, with nginx, you would need to set fastcgi_read_timeout.

Possibly also client_body_timeout or send_timeout.

And max_execution_time on PHP side.

#1428 should reduce the need for read timeouts on nginx side.

Testing it locally, it does not seem to help alone, as PHP, as well as both Apache and nginx buffer the response by default. I have opened #1430 with a more complete fix.
