Hi `ngx_pagespeed_beacon` are POST request that returns to the server info about the client, like the client viewport, screen size.... The POST request is needed for some pagespeed filters like the `resize_rendered_image_dimensions` and soo. And I have not errors with it in you page (when are not a blank page) As far as I can see, you have excluded some files (with pagespeed Disallow) from pagespeed so these files are enterely under nginx control. When a file is under pagespeed "radar" they have an etag header like etag="W/0" or etag="PSA/xxxxxx", the files that are not conpresed have etag from nginx and don´t have content encoding header. As you can see in the images, url rewrited by pagespeed are gziped, despite you have brotli, because you don´t have set `pagespeed HttpCacheCompressionLevel 0; This message `[Deprecation] chrome.loadTimes() is deprecated, instead use standardized API: Paint Timing.` comes from the filter `pagespeed EnableFilters add_instrumentation;` there is a PR [#1802](https://github.com/apache/incubator-pagespeed-mod/pull/1802) to solve these issue, but is not applied to the pgespeed module. `   ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
