Homebox web with error "Whoops, looks like soething went wrong"

Hi
I updated the firmware to version xxxxx, but when I tried to restore my backup, nothing appeared. So I erase my second honebox configuratio and created it again with an single quite mark on the name (’).
After that it always gives the error Homebox “Whoops, looks like soething went wrong” when I try to access the url https://connect.getdio.me/
Can you help me?
Best regards

Hi
I forgot to write the version. It is 2.4.3 and the update operation was ok.
Best regards
