Error during activation of web feature

Hello,
trying to activate a web feature (Plumsail Workflow Actions pack) and getting following error:
Exception: No HTTP resource was found that matches the request URI ‘https://wf-services.plumsail.com/api/SPSite/ActivateFeatureAsync’.

do you currently have service issues or what could it be else?
regards
