Hello, My issue started with sensors monitoring datastores from vSphere. The sensor type is VMware Datastore (SOAP) and it has a user that gets the data from vSphere. After an upgrade on the version of vSphere all the sensors getting data for it have entered error state : "Cannot complete login due to an incorrect user name or password." The error message is self-explanatory but seems to be incorrect. I've logged in with the PRTG user in vsphere and it's working properly. I've initially suspected that something like an AD authentication might be the cause (i've looked over this post https://kb.paessler.com/en/topic/78274-why-are-my-vmware-sensors-not-working-after-upgrading-to-vcsa-6-5-u1) but after checking with someone from out Infrastructure department that manages vsphere they said it should not be the case. At the moment I am not sure how to proceed with this, can you help ?
