Error 505 HTTP Version Not Supported / HTTP version not supported

[mehadihasan123]

Error 505 "HTTP Version Not Supported" occurs when the request from the client specifies an HTTP protocol version that the server does not support. This means that the server does not recognize or cannot work with the protocol version specified in the request.

Typically, the cause of error 505 can be the following:

The server only works with a certain version of HTTP (for example, HTTP/1.1), and the client sent a request with a different version (for example, HTTP/2.0).
The server has upgraded its HTTP version and the client is sending turkey email list requests with an outdated version.
To fix the 505 "HTTP Version Not Supported" error, you can take the following steps:

Check the protocol version: Make sure your client is sending the HTTP version that the server supports. For example, if the server only supports HTTP/1.1, make sure your client is sending the request with that version.
Upgrade the client: If the client is sending requests with an outdated version of HTTP, upgrade the client software to a newer version that supports the HTTP version required by the server.
Configure the server: If you administer the server, make sure the server is configured to support the correct version of HTTP. You may need to update the server software or change its configuration.
Contact your hosting provider: If your server is hosted remotely, contact your hosting provider for help. This may be due to the server configuration on their end.
Check compatibility: If you have third-party client or server software, make sure they are compatible with the HTTP protocol version.
It is important to note that the HTTP version is part of the protocol, and changing it may require changes on both the client and server sides. If you are unsure how to fix the 505 error, it is recommended to contact the developers or administrators who can help you with configuration and updating.
