Error on processing bearer token: Cannot invoke

[Mpho_Khumalo]

We are using SAP Business One 10 FP2311 HF1, for SAP HANA that is hosted in AWS. Recently I have this issue where I'm not able to login to my SLD, after I restart my services I am able to login to SLD but only for a few minutes then I'm not able to login. This issue also affected SAP login for all users.

When I go through the logs I see the below error:

Caused by: com.sap.b1.sdk.oidc.core.exception.B1SDKNotAuthenticatedException: Error on processing bearer token: Cannot invoke "com.sap.businessone.sld.oidc.model.IntrospectTokenResponse.isActive()" because "instroToken" is null
