Error message and false deletion

[sfpx]

2 problems that may be related

1.Starting a few days ago I sometimes get an error message (Unexpected response from Mirrorsync server) . It seems to happen when I haven't synced in a few hours. When I retry 2 seconds after the error message it works just fine....apparently anyway.

 

2.We got a wrong deletion of a record that was just inserted in the same sync.

In the log there was this line

WARNING: Deletion scanning mismatch in NodeReference for hub node FileMaker Server ... with associated spoke node Client node .. on iPhone Go ... Deleted record count (1) - extra count (0) does not equal expected missing recount count (0). This will probably lead to false deletion scans on every sync after this. 

Not sure what that means and what is the cause of this problem but I must say that it's scary.

 

I already sent the log to 360works but I'm trying my luck here as maybe someone already had this problem and knows the fix.
