Hey there, I recently (as of 4/17/2018) started out of the blue having "Searching for logon server" error happen to me after I would login to game client and then choose a server. The full screen would come up just fine then it would auto-disconnect after say 20 seconds. An error will appear on the bottom of the screen saying searching for logon server with 20 allowed attempts....well anyways, for 2 whole weeks I corresponded back and forth with SSG helpcenter in addition to reading forums, also doing google searches and reading Windows info sites. Anyways, I got it solved, here was what MY issue was. I called my ISP, they told me to turn off my "adult content blocker"---I did and it immediately did the trick. Evidently, this last update or SOMETHING has "bumped the game up a notch" in whatever rating stats get imposed on the game for adult content or something...well anyways, not that my pc didn't need it, it surely did lol, but I spent $100 having a tier 4 senior tech do a remote session on my pc here. That didn't fix the game issue however. Calling my ISP did, after I turned off "adult content blocker" on my account settings page, it was totally back to normal. And I've confirmed that was what it was. Hope this helps anyone out there.
