Synology Drive Client does not connect on Apple MacOS

Another odd issue I had recently was that my Synology Drive Connect on my Apple Macbook Air simply wouldn’t connect anymore. It just kept trying – no timeout, no “connection refused”, no error message at all. Meanwhile, Synology Drive Client on my Windows client worked fine. Both were up-to-date. At first I thought it might be a problem with the remote network I was connected to, but the issue persisted when I returned home. On my synology, the client was listed as “offline”.

Digging into this issue, it seems there was a problem with the logfiles. I am not exactly sure what the root cause was, but since the files are basically just text files, I assume they had grown too large and the client choked on them on startup.

Anyway, long story short. I stopped the drive client on my Macbook Air, then used the Terminal app to remove the log folder, located here:

/Users/{$username}/Library/Application Support/SynologyDrive/log

where, of course, {$username} was my login username on my Macbook Air. And lo and behold, upon restarting the client, it instantly connected. The client showed as “online” on my Synology DS, and files synced instantly.

I deleted the logs, but make sure to create a backup first if you think you might need them for anything.

Synology Cloudstation Pauses and Does Not Sync

The Problem:

My Cloudstation app stopped working and would not synchronize files anymore. This happened both on Windows, and on Mac.


It seemed like the app was either permanently in a “connecting” state, or pausing itself.

The solution:

It turns out that my Quick Connect became disabled at some point. I am not sure how or why; it had no account associated. I re-added that and enabled Quick Connect on my DiskStation, and Cloudstation started working again. This was especially odd because in the Cloudstation settings on my Diskstation, the status “Healthy” was displayed.
