Firmware Update from 2.63 to 2.66 failed, an no old Firmware on Cerbo

following setup 
Multiplus 2 48/3000 / 35-32 Fw. 481 
Cerbo GX 2.63 
3 US 2000 Pylontech 
MPPT 100 20 V.156 
EM24 grid meter for grid 
ET340 for PVA 
Internet connected via LAN
I Wanted to switch to firmware 2.66. After the attempt, V. 2.63 was still displayed at the Cerbo, and the connection to the VRM portal was interrupted for ca. 30 minutes.. I tried it twice and then found that the Cerbo no longer had any old backup software. 
Any ideas?
