Question regarding the ability to use geo map background. Does this expect raster /{z}/{x}/{y} tile format or is it looking for a WMS/WMTS server to query capabilities ? I have a local tile server I would like to use but it just gives invalid tile format when trying use it and the default netxms tile server does not seem to work anymore

Thanks 

It's just png tiles, yes.

But according to our monitoring and my manual check - it's just fine (e.g. https://tile.netxms.org/osm/0/0/0.png, https://tile.netxms.org/osm/14/9288/5023.png)

What kind of error you got?

Its working now I was pointing it to my WMS services not the tile service. Thanks for the reply

After testing out the geo maps some tiles do not seem to load. This happens when using both the netxms and my internal tile server.  This however does not happen when I test each tile server with Qgis everything loads just fine. I have attached a screen shot.


Update:
I had to clear the cached maptiles on the client within  .nxmc4

That's more or less expected with the current caching: the client caches tiles under .nxmc4 and doesn't invalidate them when the tile server changes, so you can get stale/missing tiles from the previous server — which is why clearing the cache fixed it for you. I've filed a ticket to key the cache by tile server URL so switching servers invalidates automatically and you won't need to clear it by hand. Thanks for tracking it down.
