AutoRemote (Solved) Tasker-->AutoRemote just one time success?

Solved. It's because battery saver in AutoRemote

I have a TASKS named "test1" : test1 --> AutoRemote Message --> IFTTT --> LINE message

PROFILES: From 09:50 every 5m Till 10:20
TASKS:test1
1.AutoRemote Message: Recipient:IFTTT, Message:FBN=:=%TIME, with Continue Task After Error checked
2.Flash :%errmsg

Result:
at time 09:50: LINE message=[IFTTT] 09.50, no %errmsg (so I think settings are all right)
at time 09:55: no LINE message, %errmsg=Timeout
10:00, 10:05......just as same at time 09:55

After I tap "test1"--> tap AutoRemote Message -->tap Configuration-->do nothing in AutoRemote Message page-->go back to Action Edit-->Task Edit-->Tasker-->Phone Desktop(to save changes), I will get the result like above(that is one time success again).

Any help? suggestion? idea? Thanks very much.
