[basicUI] "Offline: waiting for connection to become available" Message triggered by item update

Add-ons UIs

I have been plagued by this ‘Offline issue’ for some time, so I decided to do a little test and created a very simple sitemap with just a few entries from my full sitemap:

sitemap default label="Thuis" {
    Frame label="Test" {
        Text item=Current_DateTime label="Datum [%1$tA, %1$td.%1$tm.%1$tY]" icon="sun_clouds"
        Text item=Sunset_Time icon="sunset" visibility=[Sun_Elevation>=0]
        Text item=Sun_Elevation icon="sun" visibility=[Sun_Elevation>=0]
        Text item=Sun_Direction icon="sun" visibility=[Sun_Elevation>=0]
    }
}

Whenever the Astro binding updates the Current_DateTime item, the message Offline: waiting for connection to become available appears. There are no errors in the log file (although with a more extensive sitemap, I’ve seen many Jetty related errors).
There is a long standing open issue on the ESH repo related to this, and a recent issue suggesting there is a fix.
I understand this OH forum is not the place to ask for a solution, but I just wanted to inform others.

BTW, the Edge browser does not show this behaviour. However, since Microsoft will turn Edge into a Chromium based browser, I’m afraid soon all browsers will have this annoying behaviour…
