    net::ERR_HTTP2_PROTOCOL_ERROR when uploading media items

    Hi all,

    Have observed a weird issue with an Umbraco 7.14.0 site that I haven't come across before.

    Media uploads in the backoffice seem to fail about 70 or 80% of the time. There's no response back from the server, the request fails with a net::ERRHTTP2PROTOCOL_ERROR.

    • Size or type of file doesn't seem to matter
    • Happens on multiple browsers (no common plugins, etc)
    • Other Umbraco sites on the same server with similar version seem to work fine, I don't see any differences with web.config, etc
    • I don't see anything in the Umbraco log file about the failed requests

    Example of Chrome's console output:

    VM6:1 XHR failed loading: POST ""

    Looking at network tab, 0 bytes are transferred, the requests seem to fail after about 6 seconds.

    Am thinking maybe some sort of hosting env issue, but not sure where to continue looking at this one. Has anyone seen something like this before?

    Does anyone have any insight to this?
