SAP Business One certificate error in windows 10 21h2

0 Kudos

I have a problem where one of our company computers has been updated to Windows 10 21H2 and when starting SAP B1 certificate error occurs: There is a problem with the server’s security certificate. The security certificate is not from a trusted certifying authority. SAP Business One is unable to connect to the server.

SAP B1 version is 9.1 PL:04 I tried this solution but it doesn't work and I cannot risk restarting the server using this solution. I also read that the cause of this error is windows update KB3163018 but I cannot see this update in the computer

Is there any solution to this problem?

Dear lexda,

This error message often indicates the certificate is expired. Kindly follow the SAP Note 2677274 to replace the certificate for different components of your B1 cloud environment.

Kind Regards,
