Why is hexbear not working on my computer, but does work on my app?

Having trouble with hexbear on Firefox, my clean chrome build, and mobile Firefox. 504 gateway error. However my app (Boost) seems to work fine and I see many of you are still posting and I imagine from web. What is my issue? Any advice or debug steps would be appreciated because I much prefer desktop browsing. I tried deleting site data. Issue has persisted since last night.
