Hi, I've been using Confluence where I'm employed and lately, when accessing the Confluence page, this page appears every time, for a couple of seconds, and only then I can log in Confluence. This wasn't happening before (I'm using Confluence for almost 2 years now). What is the deal? Thanks.
I don't think anyone may say much more than you already can read from this screenshot. For some reason either all or some connections appear to be treated as suspicious (maybe IP is in some kind of blocklist?), so Nexusguard is checking whether your truly using a real browser or is it a bot machine. Does this problem appear when you use other device? Other laptop or smartphone and different ISP (may be Wifi AP on your smartphone or tethering) and see if it also happens on that device? Best thing would be both different ISP and device, so you would have different cookies, IP address and maybe even other device characteristics. If it would not appear then proceed with only on of those things i.e. same device, different ISP.
DDos protection to assure you're not a bot. like many cloud services. but from my view you should have asked tour local admin first.
