Mikrotik routers aren't very good and yours has probably generated a poor quality certificate which has: "certificate verify failed"

Probably, you need to upgrade your Mikrotik router firmware.

SSL routines:tls_process_server_certificate:certificate verify failed

this is something wrong with certificate. do you use changed something or update new one with difference certificate , just double check it first. make sure update time on router and client too. how do you create client and this is the first time you try to connect or you done it before?.
