Gateway - refresh failed - "The credentials provided cannot be used for the Web source."

Hi, I'm facing the same issue evething was working properly yesterday and I updated on-premises gateway to last version and now I'm not able lo connect, I follow some steps (uninstalled, deleted directories, installed again, uninstalled, installed previous version and didn't work).

I tried again a few minutes ago and same issue, I've installed last version and this is what I'm getting when I'm trying to restore a previous gateway:

Failed to update gateway details. Please try again.
This request operation sent to net.pipe://localhost/powerbi/gatewayconfiguration/service did not receive a reply within the configured timeout (00:01:00). The time allotted to this operation may have been a portion of a longer timeout. This may be because the service is still processing the operation or because the service was unable to send a reply message. Please consider increasing the operation timeout (by casting the channel/proxy to IContextChannel and setting the OperationTimeout property) and ensure that the service is able to connect to the client.
