If you use VMware VDP 5.1 or newer for your backup solution. Then you may have seen that you can’t access the /vdp-configure or /FLR recovery pages. That is because most current browsers have been updated to no longer accept old certificates that VDP uses. The fix for it is simple though, head to VMware Kb article 2111900 for the script to fix it and the installation instructions.
The fix itself only takes about 10 minutes to apply and you’ll be back up and running in no time
