You're trying to flash an older firmware than the one you're on now. It's going to fail and if it succeeds it will brick your device. you'll need to find a firmware package the same or newer than the one you're on now.
Relocking the bootloader may not be possible many have tried and failed

Could you tell me where I can find firmwares that are the same or newer than mine?

It's almost inpossible to relock your bootloader because you need to have signed that not bad boot.img and ect. As long that you don't have those files you will be unable to relock the bootloader. I have noticed the same thing when i was trying to relock mine bootloader on my moto g6.
