Recently updated VMware Cloud Director version to 10.6.1.24532667 and after this upgrade VMBR stopped working.
At this time the connection between VMBR and VMware Cloud Director was trowing the following message: This Vmware Cloud Director server does not support SDK of the following versions: 35.0, 34.0,33.0,32.0,31.0,29.0,5.5,5.1.
By checking https://<cloud_URL>/api/versions, we noticed that the oldest available version is now 37.0, so we updated VMBR from 12.1.1.156 to version 12.3.1.1139 so we could fix the API alerts. After this no more complaints about the API versioons but we are now receiving: Username or password is incorrect.
We know for sure password is working, so after checking C:\ProgramData\Veeam\Backup\Svc.VeeamBackup.log we notice that every time we issue the connection we get the following errors:

[06.06.2025 22:49:21.417] <157> Error (3) Failed to login to '{0}', '{1}'Arguments: https://<cloud_URL>:443;
[06.06.2025 22:49:21.417] <157> Error (3) There was an error deserializing the object of type com.vmware.vcloud.openapi.rest.schema.Error. Encountered unexpected character '<'. (System.Runtime.Serialization.SerializationException)

Need assistance to check the implementation and next steps.
