This is, unfortunately, because of a bigger issue that I’ve decided to not fix in one point oh, and it’s already sorted in two point oh.
In v1, the api token that desktop clients use has a lifespan of two years, time after which it becomes invalid. Why was this? So you don’t have to login from desktop clients every n-weeks or so. The web clients use a much shorter lived token that basically gets refreshed always. Alas, for the clients, there’s no easy way to implement this right now: it would require writing a lot of “dead” code (server, speckle popup, revit ui, rhino ui).
To not loose streams, I would create a new account, and share them from the old one with your new persona on hestia.
PS: I’ve written this like… 1 day ago(?) and never posted it. Sorry for the delay - was just cleaning up my tabs and found it lying there…
