OnCommand Cloud Manager Discovery Failure - On Prem Cluster



I am having some difficulties in discovering an on-prem cluster within OnCommand Cloud Manager. 1 of the SVMs show up fine, but the other 3 clusters don't display their resources. Their aggregate view looks successful and all passwords/networking seem to be in place, however after the working environment is added, whenever I click on the resources of the cluster I am met with the following error:




It will therefore never display or fully discover the SVMs, volumes, etc on this on-prem array. Both OCCM and the cluster are in the same onsite datacenter so there is nothing being attemtped yet on the AWS side. Was curious if this is a known issue, if there was a workaround, or if anyone has hit this before?


Any help is appreciated. thanks!
