User Agent does not correspond

This error appeared for some users as soon as they were redirected to the login page of ZITADEL. ZITADEL uses some cookies to identify the browser/user agent of the user, so it is able to store the active user sessions. By blocking the cookies the functions of ZITADEL will be affected.

We only found this issue with iPhone users, and it was dependent on the settings of the device.

Go to the settings of the app Safari and check in the "Experimental WebKit Features" if SameSite strict enforcement (ITP) is disabled Also check if "block all cookies" is active. If so please disable this setting.

To make sure, that your new settings will trigger, please restart your mobile phone and try it again.

Settings > Safari > Advanced > Experimental Features > disable: „SameSite strict enforcement (ITP)“

Settings > Safari > disable: "Block All cookies" Block all cookies

If you're in an self-hosting scenario with a custom domain, you need to instruct ZITADEL to use the ExternalDomain. You can find more instruction in our guide about custom domains. We also provide a guide on how to configure ZITADEL with variables from files or environment variables.
