If I had to guess, the issue is with whatever company's hosting. If that's the case, and it's impossible to reach out to them, there's very little to do except either wait it out or move elsewhere.
It's a little worse than that. The issue is with Railgun, a service our server guys include with their server deal but isn't run by them. It's apparently causing issues for reasons we don't know about and I'm trying to figure out how to stop it from causing further errors. Railgun is supposed to help load the site more efficiently so that's why the error is so prevelant. It happens every time anything loads!
Well it's been several days for me and it was happening constantly pretty much making the site completely un-checkable at all. I hope it's fixed. It's a miracle I can even make this post...
Small Update: We've had a chat with our server guys. They can't do anything either. It's as if the servers at Cloudflare have exploded or are on strike or maybe just playing Overwatch too much. I haven't a clue and we can't seem to connect to Cloudflare themselves to figure out what's going wrong. Sorry folks, we're going to have to just sit this one out till we can figure something out. I'll keep you posted. For now, please keep trying to get through and let us know when errors happen. Even better, let us know when errors happen on other sites too. It might not just be us.
If anyone's technically inclined and wants to know more, here are the docs. TL;DR: There's some wonky connection stuff happening between cloudflare and the site at the railgun level, whether that's a wire problem or a certificate problem isn't something I can say without logs.
Is it possible to disable Railgun until the issue is resolved? Slower loading times are preferable to constant errors and non-functionality.
