Versatile C++ game scraper: Skyscraper

@AlCzervik Can you try and update Skyscraper and try again? I just updated it to 3.4.4 today, and it will now tell you if the credentials are rejected.

@muldjord Updated to 3.4.4. Similar error. First I get the "Fetching limits for user 'User', just a sec..." After that, I now get "Received invalid / empty ScreenScraper server response..."

muldjord · 4 Jun 2020, 20:02

@AlCzervik Ok, that is really, really odd. Then it's not a login error. Can you please verify that it says Skyscraper 3.4.4 when you run it?

EDIT: Ah, yes, it is. Because the error message is updated with "empty". In that case, I have no idea what is going on. I can't reproduce that error here. Can you try and change your password to something else and retry it with that? I'm thinking that maybe it is an encoding error.

AlCzervik · 4 Jun 2020, 20:09

@muldjord I'll try the password change. Here's the screenshot:

@AlCzervik I can't see that, it is too small

EDIT: Nevermind, it was processing, I can see it now.

EDIT2: It actually gives me some other information. It seems that you have no connection to screenscraper.fr at all. The "Retrying request..." only happens when it receives an empty reply. This should not happen. Are you behind some weird firewall or something? Is your wifi / network connection running at all?

EDIT3: I've just tested it, right now, on my own machine. It works just fine. I'm pretty sure this is a local issue to your machine.

@muldjord I tried a larger size version but still seems super small. Regardless, you are right, that error message did change to include "empty"

AlCzervik · 6 Apr 2020, 19:18

@muldjord Okay, perhaps that is it. Wifi is running fine, that's how I updated to v3.4.4. Must be something with calling that API directly and my Wifi is blocking it.

muldjord · 4 Jun 2020, 20:22

@AlCzervik It really shouldn't be an issue. It's using https (port 443) which is always open. Otherwise you couldn't visit any encrypted webpages, which is basically all webpages. Is it possible for you to put it on wired network to test it?

AlCzervik · 6 Apr 2020, 19:29

@muldjord Unfortunately, it's all built into an arcade cabinet. I'm thinking about how else I can determine why that particular call would be getting blocked.

muldjord · 4 Jun 2020, 20:34

@AlCzervik If you at all have the chance, I would be curious to know if you could run this on any other machine. But let me know if you have further questions. Unfortunately I don't really know what else I can do at this point.

EDIT: Quick idea, do you have a DNS server registered for the connection? If not, then it won't work since it won't be able to resolve screenscraper.fr. Can you do ping www.google.com and get a response?

AlCzervik · 6 Apr 2020, 19:35

@muldjord pinging google worked just fine. Tell me more about the DNS server issue?

muldjord · 4 Jun 2020, 20:36

@AlCzervik No need. If you can ping www.google.com it is not the issue. Try doing ping www.screenscraper.frjust for the heck of it. But it's not pinging on port 443 so it doesn't really tell us if that's the issue.

AlCzervik · 6 Apr 2020, 19:37

@muldjord pinging screenscraper worked too

muldjord · 4 Jun 2020, 20:38

@AlCzervik What happens if you do telnet www.screenscraper.fr 443 and then type test and press enter? That will connect to the server on port 443 and send testto it, which should result in a 400 Bad Request reply.

AlCzervik · 6 Apr 2020, 19:39

@muldjord telnet command not found

muldjord · 6 Apr 2020, 19:40

@AlCzervik Then you should be able to do sudo apt install telnet

AlCzervik · 6 Apr 2020, 19:43

@muldjord Done. Sorry, was doing that too. Okay, I got the 400 Bad Request reply once I successfully installed telnet

muldjord · 4 Jun 2020, 20:44

@AlCzervik I am very puzzled now. Then you have access to the server over port 443 (https) which means the connection works. But for some reason it always responds to you with an empty reply. Which it doesn't do for me here.

AlCzervik · 6 Apr 2020, 19:45

@muldjord Could it be my version of retro pie or some other inconsistency I have installed with your latest skyscraper version?

muldjord · 6 Apr 2020, 19:46

@AlCzervik I can't come up with anything that would cause this. What happens if you remove the credentials entirely from config.ini? Do you get the service closed for unregistered users reply when scraping games?
