VPLS interface goes down and not up again

Good morning.
I have some VPLS that won’t re-connect to your peer when one side goes down for any reason (energy problems, ptp problems, etc). I use mikrotik version 7.12.1 to do that VPLS.

On A side (VPLS destination)

/mpls interface
add disabled=no interface=sfp-sfpplus1-328-MPLS
/mpls ldp
add disabled=no loop-detect=yes lsr-id=xxx.yyy.zzz.aaa transport-addresses=xxx.yyy.zzz.aaa
/mpls ldp interface
add disabled=no interface=sfp-sfpplus1-MPLS transport-addresses=xxx.yyy.zzz.aaa

interface vpls
add arp=enabled disabled=no mac-address=02:DB:64:94:83:1F mtu=1500 name=vpls-P1 peer=xxx.yyy.zzz.bbb pw-l2mtu=1500 pw-type=raw-ethernet vpls-id=20:0

On B side (VPLS router)

/mpls ldp
add disabled=no loop-detect=yes lsr-id=xxx.yyy.zzz.bbb transport-addresses=xxx.yyy.zzz.bbb

/interface vpls
add arp=enabled disabled=no mac-address=02:A4:B4:98:0A:CD mtu=1500 name=vpls-CONCENTRATOR peer=xxx.yyy.zzz.aaa vpls-id=20:0

Any tip will be appreciated
