B4J Question [ABMaterial] No Connection Toast Error

[Harris]

Suddenly, I get the error listed below, along with a Red Toast - No Connection (4 times) for each page in the public domain. In the member section, this does not show any of the same problems. Weird...
I am not using latest B4J 5.80.

This happen to a site (VPS) where I have not updated anything and it never exhibited this behaviour before.???

I am seeing the 4 No Connection toasts when I access the feedback app, they appear only on the root page: 81.165.232.188:8080/feedback/

That's correct. Exactly what I get - for each page in the public section. Other than that, it works fine there after.
