Not all website components are loaded successfully - ingress-nginx 499 errors
@maarten reported that during his work on nextcloud!157 (merged) he noticed that the taiko tests are quite flaky. Sometimes icons doesn't appear, and the OO test fails for unknown reasons sometimes.
I tried to debug this with the Firefox web developer tools (Network tab) and it shows that on one try on staging, the app-themed.svg
didn't load as seen in the screenshot below:
Looking at the ingress-nginx logs there's this entry with a 499 error code:
84.158.175.229 - - [28/Apr/2022:08:38:12 +0000] "GET /css/core/9568-0fe1-css-variables.css?v=b92d206521717ac032f8aa58d3c7ff2f- HTTP/2.0" 499 0 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:99.0) Gecko/20100101 Firefox/99.0" 70 0.010 [stackspin-apps-nc-nextcloud-8080] [] 10.42.0.12:80 0 0.008 - 9019734fa1b3a4ef049dd114b2d2896b
It looks like http error code 499 is a nginx specific error code, which indicates that the client closed the connection. So very likely a client side timeout.
