This is typically caused by a Web Site presenting a content encoding header of one type, and then encoding the data differently. The cause of this error message is a web server whose HTTP response headers indicate that it will be responding with one type of encoding, but instead responds with a different type of encoding. For example, what is commonly seen is that a web server returns a gzip compressed object, but the content is actually text.

However, in the specific scenario described above, if you want to allow the content from the web server to be delivered to the user you can implement the following policy based workaround. This workaround removes the header in the client request indicating that the client can receive encoded content and instead forces the server to respond with the file in its original form.

HTTP data is compressed before it is sent from the server: spe07 error analysis browsers will announce what methods are supported to the server before downloading the correct format; browsers that do not support compliant compression method will download uncompressed data. The most common compression schemes include gzip and Brotli ; however, a full list of available schemes is maintained by the IANA. There are two different ways compression can be done in HTTP.
