Question:
Why does the SpectroSERVER crash with VpnIHVpnManager in the stack trace file after upgrading from Spectrum 10.1.x to Spectrum 10.2.x?
Environment:
Spectrum 10.2.x
Answer:
The Database catalog and associations are modified for VPN Manager from 10.1.1 and above. As with the upgrade there is scope of alignment mismatch of DB structure with internal tables. Therefore it is recommended to delete all the Vpn, VpnSite and RT models through locator search and re-discover them from the VPN Manager.   After doing this there should be no further problems.
