Very strangely when i sat down to work on a logging issue (dedicated server on playfab does not add the .log extension to the file)… I was able to connect and open the map!
However integer overflow was causing crashing which is a previous issues I resolved through this post. I have dev4/ loaded with this change and I can connect with both Chrome and Firefox.
The problem now seems to be major lag or network performance issues.
Direct messaging you some log files but you should be able to see them yourself once logging in and viewing the browser console.
Also - I will update with a windows client test shortly.
