Requests are stuck - invalid credentials

Hi Team,

I just integrated my vRA 7.3 with Istanbul SNOW instance using plug-in 3.0. I am able to request (and approve) services from the vRA catalog, however requests are stuck. See screenshot below.

In the plugin log I can see the following error message, however I am not able to identify what are the invalid credentials.

REST call error found inside VRASNRequestUtil.getTemplateViaRest: Method failed: (/catalog-service/api/consumer/entitledCatalogItems/94748c1b-40fa-4ec0-a239-6ef0807b73c6/requests/template) with code: 401 - Invalid username/password combo

Thanks

Paolo
