Problem Loading into game.

[TULOA]

With my code changed to a repl.it tested URL Detection code the following function seems to be causing WoW to not get past the loading screen:

function URLFind(str)
    local _results = {}
    local _x = 0
    local isFound = false
    while _x <= #str do
        
        url = ""
        pos = 0
        url =  string.match(str, "https?://[%w-_%.%?%.:/%+=&]+", _x)
        pos = string.find(str, "https?://[%w-_%.%?%.:/%+=&]+", _x)
        --print(url)
        if url == nil then
            --Didnt find fully matched URL so lets try a shorter one.
            --url = string.match(str, "[^\.][^\s].*\.\.".."com".."[/]*\s?", _x)
            url = string.match(str, "[%w-_%.%?%.:/%+=&]+", _x)
            pos = string.find(str, "[%w-_%.%?%.:/%+=&]+", _x)
            
        end
        if url ~= nil then
            if url:sub(1,1) == " " then
                url = url:sub(2, #str)
                pos = pos + 1
            end
            tinsert(_results, {url, pos})
            --print(url.." | "..pos)
            _x = pos + #url
            --print("Adding. Next X: ".._x)
			isFound = true
        end
    end
    return isFound, _results
end

Anyone have an idea of why it would be doing that?
