I don't think so, since OP mentioned Arc 3.2 without any Nginx. I just tried it and I'm able to reproduce this issue with just the official branch in anarki (which is identical to Arc 3.2) without any Nginx.
Arc 3.2 doesn't get very frequent updates, but we should probably fix this in the stable branch. It shows the same error, and also has some errors in the log. Unfortunately I'm not sure when I can get to this. I've been having some RSI issues and time at the computer is limited at the moment.
