• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Issue "Err_http2_protocol_error" error

Hi all,

On one of our Plesk servers, we have a website that allows users to upload files.
Since the beginning of december, some users have errors during the upload. It's a small number and it's random. Even with small files (500 KB for example).

The error is: "err_http2_protocol_error"

We have found information that can be a problem with Chrome and GZIP but GZIP is not active on this website.

Do you have an idea of the problem and how can we resolve it?
