Well deleting the internet connection didn't help, but switching to self-hosted did! =)
I'm not sure if I should conclude my ISP is blocking the exploit? Or perhaps the anti-malware feature on my router.
I'm running 5.5.1 US. Everything was working fine a few days ago, now when I try to launch the browser exploit from any number of different sites I'm getting an error message 112-2600.
Any suggestions please?
