I checked on my site, www.macrofoods.ca this morning and it was working (a few hours ago). I checked again and when I go to it, it says there's a 502-backend error. I tried refreshing the web app and I get the message, "Your webapp took a long time to reload. It probably reloaded, but we were unable to check it."
I haven't changed anything from this morning, was there a way to fix this?
