Hello,
Sometimes when browsing the forum, sometimes when I post, I get a 502 Gateway Error, which does not go away until waiting until a random amount of time passes and the website working again.
Unfortunately this occured while I was trying to make a post earlier, and had resulted in me triple or quadruple posting the same post, without me noticing. Specifically, each time I tried to post, it gave me a Gateway Error, so I was not sure if it even made my post in the first place.
Obviously this is something which can create a great misunderstanding between the rules and innocent forum posters. It might be a good idea to look into this, so that users are not wrongfully infracted or banned over it.
