  • Support for BIND DNS has been removed from Plesk for Windows due to security and maintenance risks.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS.

Issue "Err_http2_protocol_error" error

Erwan

Regular Pleskian
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?
