Heya folks. Was gonna see how the game works on my tablet however got this when I tried.
When I made my account to post this I saw the Game was in maintenance so that could be the cause so I'll try again when it's up again.
Chrome
Sero pro 7 (android)

I am honestly not sure why this happens sometimes. I'll have to do some testing and try to dupe this. All I know for sure is mine looks like this:

I assumed it was a false flag since I encountered nothing malicious with my desktop but never hurts to drop a note and all that.

One idea: Are you on a public WiFi? Maybe it's trying to tell you that wifi isn't secure. I know people used to sit around places like Starbucks and steal passwords with some software I forget the name of. Basically it would detect anyone that navigated to facebook and hijack their session. Then you could post as them, etc.

No it's my home one, secured and all that.
Firefox seems to recognize the security certificate.
Though it seems with the current game settings available, my tablet screen is too small to really play on

Mob(s) hp hides behind my skill bar.(also can't see my hp either when choosing skills)
Ill add a quick SS here in a sec.

From what I understand the game is pretty fresh still so no biggie on making it entirely tablet friendly right away! Just figured I'd try it then give some feed back alongside the security flag.

Yes, the game definitely has a ways to go for tablets... it's on my to-do list!
