@Hulk It's impossible to know from the few details provided what the reason might be. Only after you've disabled all firewall and anti-virus software it actually makes sense to investigate this further, because if they cause the issue WebIQ can do nothing about that. Like @HmiGuide for me this also sounds more like the issue that's already been fixed a couple of weeks ago.
In general, whenever you're facing any issue you should try to reproduce it with the latest version before reporting it as it might already have been fixed and always provide as much information as possible (WebIQ version, ctrlX firmware version, connect.log, designer.log, affected HMI, detailed description of the issue so that someone who does not know your HMI can reproduce it. Because if we can't reproduce it, we can't fix it.)
Also, can you please no comment on a solved issue with when it's unclear if it's the same cause - simply create a new thread for that.
