Backup failed due to license issue after Windows update

Hello everyone.

This is an Acronis 11.7 Advanced (Windows) issue with my client.
My client updated Acronis Management Server (Windows Server 2012 R2) on July 24, 2022.
Update Codes: KB5015874, KB5016264, KB5014637

And from then on, backups of all Acronis agent devices, including the management server itself, fail with a License error message.
(There is a problem with the license. Click "Help > Change License" to check the license assigned to your machine.)

So I went to "Help > Licensing" and saw that the "License for Disk/File Backup" item said "Unlicensed (Cloud Backup Only)".

I clicked the "Specify" button and said "Acronis license server could not be found in "admin server name". Please check the address you specified and the connection status with the license server." message was output.

So I clicked "Enter License" and entered the license key, but the message "SSL Connection Failed / certificate verify failed" was displayed and I could not add a license.

What should I check and what should I do to solve this problem?
