We’re suddenly seeing a number of HTTP 400 errors on
new-reg requests to the v1 API.
Request body (pre-JWS):
Response headers (400 Bad Request):
- Date: Tue, 24 Sep 2019 13:44:29 GMT
- Server: nginx
- Connection: close
- Content-length: 150
- Content-type: text/html
<html> <head><title>400 Bad Request</title></head> <body> <center><h1>400 Bad Request</h1></center> <hr><center>nginx</center> </body> </html>
This was from IPv4 184.108.40.206, but it’s happening on many of our servers (and our clients’ servers).
Please advise? We haven’t changed our implementation. This problem didn’t appear until last night, a few hours after we received notice of the recent CDN change.
