I can't get to the Facebook page on my android

Hello,
I have a problem that more often than not occurs. When I try load the webpage it comes a warning/popup/something saying a safe connaction couldn't be made. And then it stops loading. I've tried facebook.com instead of m.facebook.com, but it only redirect. I don't have the facebook app and I usually have the gps off. My facebook on my laptop is working completely fine, so I could use that, but you can't use that on the bus.
