I upgraded to 8.1.26 version and installed without problem. When I try to open OPC Client and OPC UA section of Ignition Gateway page, page is refreshing constantly and I can't even touch anything. But the other sections working perfectly. We'll make an integration demo and this issue blocking us.
Note: I'm trying with the different versions with install/uninstall but nothing changed at the moment.
Thank in advance for your advices.
