Can't access the settings of Hosted Tile Layer on the Portal

[GuillaumeRuelle]

Hi,

I added a VTPK on my portal (directly from the machine, and later from ArcGIS PRO), then I published it as a hosted Tile Layer from the portal. 

Now, when I try to access its settings, the web page keeps loading forever. This issue doesn't appear if I try to reach the settings of hosted feature layer.

Hosting server seems to be correctly configured (checked on portaladmin).

The checkUrl command was run, with httpsStatusCode of 200.

No errors in the Portal logs.

On the server/manager, we get this warning: Error in getting ItemInfo for service <hosted/name_of_the_service>  null

Any help appreciated !

Solved : I was using a wrong wildcard expression in my "allowedProxyHosts" (portaladmin>security>config)

*.domain.com replaced by (.*).domain.com
