HTTP 406 responses

From multiple IP addresses in AS55836, I receive the following response:

$ curl -i https://ipinfo.io/ 
HTTP/2 406 
server: nginx/1.24.0
date: Sun, 02 Jun 2024 06:13:15 GMT
content-type: application/octet-stream
content-length: 111
via: 1.1 google
strict-transport-security: max-age=2592000; includeSubDomains
alt-svc: h3=":443"; ma=2592000,h3-29=":443"; ma=2592000

{"error": 406, "data": "If you believe you've received this request in error, please open a support request."}

Unfortunately; it just doesn’t affect the API, the website is also not accessible.

I can provide the specific IP addresses through direct messages on request.
Thank you.
