I'd love some really smart networking people to help solve this issue. Every now and again those in my house wanting to play RotMG experience the darned "Socket-Server Security: Error #2048" error. We can log in, but when we try to go to the Nexus the character runs a long time before the error shows up. We never get to the Nexus.
Things we've tried (many of which are suggested as solutions to the problem on different forums):
- Rebooting the router.
- Turning the firewall entirely off on the router.
- Ensuring all computers have accurate time/date.
- Rebooting the computers.
- Using Firefox, Safari, Chrome, and Flash Projector.
- Selecting different servers, both "Best Server" and different specific ones.
- Using multiple different computers.
- Trying to log in repeatedly over multiple hours.
No glory with any of them. The full text of the error message is:
Socket-Server Security: Error #2048. Please open port 2050 in your firewall and/or router settings and try again
Connection failed! Retrying…
While attempting to connect (and experiencing the error) using the Flash Projector I used
lsofrepeatedly to check out the connections. And guess what? A connection is fully established to remote port 2050, repeatedly:

The last time this happened was on the heels of the Mother's Day server fiasco. After DECA claimed the servers were up, I experienced this problem for a few hours. It magically got better on its own. I mention this to point out that it's not a persistent configuration problem with my home network. With no networking changes we have played the game nightly for hours on multiple computers before and after the error.
This time it's happening after many city-wide power outages. I mention this in case it happens to be an issue with my ISP's configuration after bring up.
Any suggestions on how to further debug—and ultimately solve—this issue?
