EST test server testrfc7030 returns bad request

[mobe1]

Hi,

There was a time I could access the website with a number of instructions to follow for each use-case

• http basic auth
• PoP enforcement with challenge password (tls-unique value)
• etc.

Now, when i try to access EST test server -> https://testrfc7030.com/ I get the following

Error 400: Bad Request
An unknown error has occured.

Is the service down ?
