Everything went normal during study of Online Book .
Then sudden I tried to enter Online Book during Notebook session and get IP problem. All other connection are performed as normal. I have access of all my files in the Wolfram Cloud.
I cleaned cookies, ipconfig /renew, restart…
I changed also DNS configuration. No solution. www.test.wolfram.com is not resolved!

Thanks for reporting this! It seems to be an inconsistency in the server configuration after the recent Cloud 1.55 release. The “online book” (Elementary Introduction to the Wolfram Language) and the documentation center are pointing to the wrong URLs. We’re working on a fix.
In the meanwhile, you can reach the book directly here: An Elementary Introduction to the Wolfram Language by Stephen Wolfram
and the Documentation Center is available here: Wolfram Language & System Documentation Center
Sorry for the inconvenience.
This is fixed now.
Functionality is restored. Thanks
