Splash 3.5 docker image hangs forever

[r0oth3x49]

First of thanks you so much for this great project.

I am facing an issue with latest splash docker image 3.5 as well as 3.4 both. when we try to run it against https://securityfoster.com it never responds back, even timeout is not triggering, i tried the following lua_script (default ones) within the splash.

function main(splash, args)
  local ok, result = splash:with_timeout(function()
    -- try commenting out splash:wait(3)
    -- splash:wait(3)
    assert(splash:go(args.url))
  end, 2)

  if not ok then
    if result == "timeout_over" then
      return "Cannot navigate to the url within 2 seconds"
    else
      return result
    end
  end
  return "Navigated to the url within 2 seconds"
end

and

function main(splash, args)
  assert(splash:go(args.url))
  assert(splash:wait(0.5))
  return {
    html = splash:html(),
    png = splash:png(),
    har = splash:har(),
  }
end

with both of the script splash is not responding and hangs, I have to stop and re-run the image. OS: Ubuntu 20.04.6 LTS

Well, in my case splash seems to hang at startup. Just tells me that it is listening on port 8050 and nothing else happens.

Same problem with other web pages (alikeskin org) It seems splash:wait(3) parameter brokes somethings. Can you try without wait parameter? It worked for me.

Verbose log with wait parameter.

It seems there is a general problem with splash wait parameter and web pages use gstatic.com

It can be same issue with this: https://github.com/scrapinghub/splash/issues/1167
