All out of nowhere our website did not longer load CSS.
The Chrome browser console showed
Error 330 (net::ERR_CONTENT_DECODING_FAILED)
With the httpie tool a similar error:
$ http "https://www.example.com/A.theme,,__dist,,_css,,_all.css,,q1669307021+typo3conf,,_ext,,_tiny_png,,_Resources,,_Public,,_Stylesheet,,_lightbox.css,,q1642153071+typo3conf,,_ext,,_example_theme,,_Resources,,_Public,,_Css,,_lazy-loading.css,,q1669307007+typo3conf,,_ext,,_theme,,_Resources,,_Public,,_Css,,_KeSearch,,_pagination.css,,q1642153071+typo3conf,,_ext[...],Mcc.Trdmt7Jhh6.css.pagespeed.cf.IAdiJ5fbh7.css"

We were able to solve this problem by
sudo touch /var/cache/mod_pagespeed/cache.flush
But we are wondering if this could happen again.
Did anybody see such a problem before?
