New to Syncthing, Leaving Syncthing

I have also seen something like this and I also agree that it is a little bit less of informations. When dealing with Syncthing and Synology, there are a few simple rules, to which there are also enough contributions, including mine.

I recently had 4, now 3 Synology DS with Syncthing installed. With the latest Syncthing v1.4.2 it runs flawlessly and everything is synchronized. I do some cross-checks from time to time, so I’m sure.

To get further, some information are needed. Whether you use the SynoCommunity package or the Syncthing package that has been available since January:

as there described in the documentation, it must be ensured in any case that the rights have been granted.

In addition, on Synology side the individual peers under Edit > Advanced > Permissions Ignore must be activated (checkmark), otherwise the described effects can occur.

Then the to be synchronized scope would be very important, since the RAM memory with 256 MB in the DS212j limits the matter quite quickly. This could also be one of the reasons why it is not working properly.
