Had to change arcgisserver to ags, as per below:
Only an issue on Android since 10.4.2 upgrade.
iOS still displaying and downloading basemaps from arcgissserver just fine.
Any ideas why?
Was anything else changed when you changed your proxy/web adaptor from arcgisserver to ags? I see the old server uses web-tier authentication. I do not know what the ags link uses as that looks to be blocked for now.
Do other services fail to download or display coming from the arcgisserver url?
No changes made, only upgrade to Android v10.4.2.
- arcgisserver has integrated Windows Authentication (IWA)
- ags has anonymous authentication
All other services from arcgisserver work fine, as long as they are Feature Services. If they were Map Services, they failed.
Any other thoughts?
I would make sure this setting is enabled:
Available map and image cache properties—Documentation | ArcGIS Enterprise
What errors do you receive when trying to download?
Can you be more specific about which setting? There is a lot of detail in that webpage. Thanks.
Here is a screenshot of the error - the map/image displays only as grid.
Note, you can still pick a work area and map detail, and it downloads successfully - this didn't happen last time I tried, it just failed to download.
Thank you for the screenshot. When you open the map and do not attempt to download it, do you see the basemap? Do you see the basemap over wifi or internal wifi? I see that you are on LTE right now, correct?
When I open the map, I cannot see the basemap - please see screenshot.
I'm using wifi - I've tried multiple networks.
I think the Vo LTE thing is something to do with phone using 4G/3G - I've done a random google.
I also just tried going to flight mode and connecting to wifi, to disable phone reception/data - still same problem.
Last thought is I forgot to mention that we're still on Portal 10.3.1 - haven't managed to upgrade yet.
If you log into ArcGIS Online on your phone through your browser and access the map, do you see the basemap?
We don't use ArcGIS Online.
We use ArcMap to publish services, the use Portal for ArcGIS to create our maps.
If I look at the map in Portal on my phone I can see the basemap when it has arcgisserver in URL.
I think this issue may be best resolved by contacting ESRI Support. This will assist you in handling the issue in a quicker manner
