Forum "Bad Gateway" issue

[Rilex]

It hasn't done it in awhile, and only seems to occur when a influx of people are on it at the same time, making the bandwidth of the server and having you constantly refresh. I think it could be Nginx issue on the server that this site is hosted on. I used to have this issue with some of the websites I host personally, and I just recently updated to the newest Apache version. Just a thought, correct me If I'm wrong If someone ends up finding the solution to the problem.
