This is the following configuration we are using.

browser.cache.disk.capacity = 2048576
browser.cache.disk.parent_directory = <CacheDisk_Path>
browser.cache.check_doc_frequency = 3
network.http.rcwn.enabled = false
browser.cache.disk.smart_size.enabled = false

I couldn't find the issue in the logs. Kershaw will also take a look

Sorry for the long delay.
This seems to be the reason of load failure:

2024-01-12 08:22:04.852368 UTC - [Parent 11340: Socket Thread]: I/nsHttp Http2Session 7f3fc7a1e800 buffering frame header read failure 804b0014

The log indicates that the HTTP/2 connection was closed due to NS_ERROR_NET_RESET (804b0014), which usually means the server reset the connection.

The log lacks information from the socket layer, so I can't determine the root cause. Could you try to obtain an HTTP log (with MOZ_LOG=timestamp,sync,nsHttp:5,cache2:5,nsSocketTransport:5,nsHostResolver:5) along with a Wireshark trace? This will help us confirm if the server is indeed closing the connection.

Thank you.

Closing due to lack of information. If we can get more logs then we can re-open, thank you.
