SUMMARY I have problems with my router in DNS resolution currently. One symptom is that POP3 of my mail provider times out, hence also his Cal Dav resource / server times out. So far so good, but when reinstated working DNS I found out, all my appointment of the resource vanished. Hence I controlled and the two online resources resulted deselected, after selecting them again, with working DNS all turns to normal. STEPS TO REPRODUCE 1. have time outing DNS server 2. use Kontakt with webDav Kalender and autostart session. 3. online resource will be deactivated (and stay so) without warning. OBSERVED RESULT resources are deactivated not temporarily but permanently without warning EXPECTED RESULT resources should not deactivate without user interaction and a warning of non availability should be shortly displayed. Service should be restored once the connection is restored.
