Your Duet rejected the HTTP request --> problem

As from yesterday, i get this error:
"page not found Check that the SD card is mounted and has the correct files in its /www folder"I try to unplug 24V main power supply, unplug USB, reconnect everything and it worked for a while.
Then I run homing and got this error :
G28
Error: Cannot read file, error code 1
after that i lost my files in G-codes directory....It appears that i have to replace the SD card and reinstall firmware to solve this problem ?.
The only thing i am concern of is this.
Would it be possible that the SD card got damaged because of the setup that i use for triggering vacuum pump.. To be more exact. i have hooked up my external circuit that is triggering 24V ( external 24V adapter not connected to duet ) to my vacuum injector and replaced one jummper under FAN.
To manage this to work HW setup is made on the way like i showed in picture. Could this anyhow effect to duet board ? I dont think that this has anything to do with it but who knows...Gcode setup:
G4 P150
M106 S255

Your mosfet board is unusual in that it does not use an optically isolated input. Therefore you must be using a common ground between the Duet and the supply to the pump. SD cards are fragile and it's possible that a ground transient damaged the SD card. I recommend that you change to a mosfet board with optically isolated input.
You need to replace the SD card, but you should not need to re-install the firmware unless the transient has also corrupted flash memory.

optically isolated input
ok. i can do that.I have installed new sd card and copy / pasted all backup data and it look that everything is OK.
