Omniscope Mobile in 2.9 Plus can now be configured to automatically reload should it receive a HTTP 401 or 403, e.g. to indicate a login session (as might be provided by a 3rd party reverse proxy such as keycloak) has expired. This creates a better experience rather than showing an error dialog.

You can enable this by ticking "Reload on AJAX auth fail" in the Omniscope Web server configuration dialog.

Alternatively, edit the server's config.xml file:
<mobilewebserver ... reloadOnAjaxAuthFail="true" ...>

Available in tonight's build - 2.9 Plus b1833 and later.
