Hi,
since now half a Year, i've got the problem, that parts of the Webadmin are suddenly unreachable, only showing a Red Box saying "Unable to load page. Check your network connection." While other Tabs are reachable.
For example the Firewall Rules Tab in XG 18.0 is not working, while configuring SSL/TLS Decryption rules is working as usually.
Before the update I've only had this problem with the E-Mail Configuration, but now the "Firewall Rules" and the "DoS Attacks" Pages do not work, while E-Mail configuration is working fine. Restarting the Appliance don't solve the Problem at all. After some days the problem had vanished in the past, and occured a few days later again.
Since configuring Firewall Rules is essential waiting is no option anymore. The Problem also occures again after a few days when reinstalling the XG.
Here are some screenshots:
