The revocation function was unable to check revocation because the revocation server was offline
Translated humorously into Czech as Funkce zrušení nemohla zkontrolovat zrušení, protože server pro zrušení byl offline.
If the issue is with the certification authority, the following registry modification will help you. In HKLM\System\CCS\Services\SSTPSvc\Parameters create a new DWORD (32-bit) named NoCertRevocationCheck with a value of 1.The provided solution should be implemented only for the necessary period!
