I'm testing eM client for OX appsuite and it has been working fine for couple of weeks. Now it throws an error message saying 'eM client for OX app suite currently cannot be used with your account' and goes offline.eM client log says 'forced offine is true'.

I've set the com.openexchange.capability.emclient_basic capability for the whole context and we have a valid license. I've also tried an emclient.properties file setting com.openexchange.capability.emclient_basic=true

Any help is appreciated.
