That error.. again

[MossyPaws (OP)]

Damn error isn't letting me on the server- or any server.

This is a recurring issue, and I was wondering if any of you have any insight on it?

It's odd that you'd get that error. 403 is a blanket error code for when a server simply refuses you access, but does not give a reason.
You could search "403 error minecraft"

You could also unplug your router and/or modem for 10 or so seconds and plug them back in to see if that works.
