After DC Slave rejoin: Portal dysfunctional

UCS - Univention Corporate Server
#1

Hi,

unluckily I had to rejoin a DC Slave. Now the portal page on the slave isn’t working anymore. Only the picture without entries is shown. There is no redirect to the login page.

But it’s possible to login on the local UMC via SAML.

There are some logs in the firefox:

Diese Seite verwendet die nicht standardisierte Eigenschaft "zoom". Stattdessen sollte calc() in den entsprechenden Eigenschaftswerten oder "transform" zusammen mit "transform-origin: 0 0" verwendet werden. portal
Synchrone XMLHttpRequests am Haupt-Thread sollte nicht mehr verwendet werden, weil es nachteilige Effekte für das Erlebnis der Endbenutzer hat. Für weitere Hilfe siehe http://xhr.spec.whatwg.org/ dojo.js.uncompressed.js:348:4
Could not load JSON data from /univention/portal/portal.json: RequestError: Unable to load /univention/portal/portal.json?v=2.0.2-4 status: 500 and an error in handleAs: transformation of response dojo.js.uncompressed.js:49149:4
TypeError: portalJson.portal is undefined main.js:1217:8

Cheers,
Stefan

Some logs of the portal server:

The /var/cache/univention-portal/groups.json was corrupted. I’ve copied it from the DC Master and the portal is working again.

I expect that’s possible to force the listener to recreate the file?
