I had this problem (same hardware) when testing v5.x and going forth & back to v4.17. ssh service was declared invalid. One difference with you, IP range for clients wasn't limited for ssh.
When rebooting with v4, I notice some message one console about ssh server keys being generated... each boot.

What I did to solve this (it's absolutly no "clean" nor official, but couldn't find another way): upload rOS v5.0 or rc12 unified npk. Do upgrade reboot. upload v4.17 unified npk, Do downgrade reboot... And should be solved. Another reboot (with v4.17 now) should not show any ssh key related message on console.

it fixed!! thanks

from your answer, I thought, if we need downgrade , then we must downgrade from 5.1->4.17, we should go 5.0 then 4.17.
if it was true, what if I want to downgrade to 3.30,that many versions I have to do it one by one?

Sorry, I'm relatively new to routerOS, I don't know any version before 4.17, so I can't deduce some general tip from this.
