Server Version#: 1.25.2.5319  
M1 Mac Mini

I’m seeing this error popping up in my [server logs:](https://support.plex.tv/articles/200250417-plex-media-server-log-files/)

```auto
[HttpHeader] invalid 'X-Plex-Device-Name' header value (Dust’s Server)

```

“Dust’s Server” is the name of the server where this error is being generated. Are apostrophes not allowed for some reason? 🤔
