Hi @<1716987943555436544:profile|BeefyDolphin18> , the SDK does indeed use a token, as does the UI. The UI has the token stored in a cookie, which should be sent to the fileserver by the browser when making the request. I suspect that the cookie domain in your case is not your domain name (qscape.app) but a more specific subdomain for the webapp (probably clearml-app.qscape.app?)
You can easily check that by looking at the cookies set for the clearml webapp in the browser and check the domain setting there.
The .Values.clearml.cookieDomain setting in the clearml chart value overrides will allow you to specify the correct domain (this should be your base domain, so probably qscape.app) - once you do that and redeploy the server, you can log out of the UI, log back in and the cookie should be set and available to the fileserver.
