Not sure why, but I am getting this message when I try to login on my laptop but not on my desktop: There was an error completing your request. Please try again. I have tried reinstalling and checking my firewall. I have seen that this may be an issue on their end that was resolved a year ago? Any one got any links to others' resolutions/ dev posts on the issue?
Add launchpad.exe & eqgame.exe to the exceptions or white-list for your anti-virus & firewall - especially if you are using Windows Defender as this is known to often block connections to EQ.
