I keep having this black bar appear at the bottom of the basic site map page.
[SSE subscription failed: running in fallback mode]
Ive searched around, and all the articles where this error is happening don’t seem to apply to me. No reverse proxy etc.
Openhab 2.5 is running on a Pi 4, happening in chrome and safari browser running on Mac book. The error persists even if I remove all but 1 item in the site map.
