My superhub was working just peachy yesterday (which says something considering what a piece of [censored] it is!). However this morning I couldn't connect to any newsgroup servers with my existing clients. Strange I thought, maybe an issue with my newsgroup provider, so I emailed them and they confirmed everything was working fine and my account was up to date.
After rebooting router, clearing dns cache, and reinstalled newsleecher I finally stumbled across the problem. From this morning it appears that if I want to connect to any SSL server I have to set my superhub firewall to LOW, or it refuses to connect at all.
