Fixing Synology DS413 slow transfer speeds

Synology DS413

I have an ageing Synology Disk Station 412 NAS. It used to be capable of very reasonable 100MB/s transfer speed. At some point, I enabled share encryption, which reduced transfer speeds by about half. It was chugging along like this for quite some time but then noticed that speeds got even slower. After a quick test, I found that upload to an encrypted share was lingering at around 10MB/s, downloads were maybe double of that.

Synology NAS Let's Encrypt Certificate error: "The Operation Failed"


Trying to add Let's Encrypt certificate on Synology DS918+. The process fails with error:

The operation failed. Please log in to DSM again and retry.

The operation failed. Please log in to DSM again and retry.

There are no obvious reasons for the error. Port 80 is open, Synology Log Center doesn't have any clues.

Batch delete multiple videos in YouTube Studio

Currently (as of June 2019), there is no option in the new YouTube Studio (still in Beta) to batch delete multiple videos at once. You have to click the Options button (three vertical dots) next to each video and select Delete.
