alocacoc Posted January 29, 2017 Share Posted January 29, 2017 Hi There are some websites which gives me the answer 502 Bad Gateway on Windows 7. I red, there is nothing to do on the client side since the error is somewhere on a server. BUT, I'm able to open the same websites on my android smartphone. Connected by WiFi. Therefore methinks, is something wrong on my local pc. Any suggestions? Link to comment Share on other sites More sharing options...
Chicog Posted January 29, 2017 Share Posted January 29, 2017 Do they give you this every single time? If so, have you tried something like Browsec on Chrome? Link to comment Share on other sites More sharing options...
alocacoc Posted January 29, 2017 Author Share Posted January 29, 2017 Yes, every single time. I tried it on Firefox and Internet Explorer. Link to comment Share on other sites More sharing options...

I say that because sometimes I get that with Browsec and I don't when it's turned off, or vice versa. Link to comment Share on other sites More sharing options...
alocacoc Posted January 29, 2017 Author Share Posted January 29, 2017 No chrome. Even not installed. I guess it's rather something wrong somewhere within the windows. Link to comment Share on other sites More sharing options...
Chicog Posted January 29, 2017 Share Posted January 29, 2017 There are a lot of potential reasons, but try Browsec with Firefox and see if that fixes it:https://addons.mozilla.org/en-us/firefox/addon/browsec/ Link to comment Share on other sites More sharing options...

Chicog Posted January 29, 2017 Share Posted January 29, 2017 Sometimes it's out of your hands, e.g. if your ISP is using a badly configured proxy of some kind. (What chance of that in Thailand eh?). Link to comment Share on other sites More sharing options...
johng Posted January 29, 2017 Share Posted January 29, 2017 I've had the bad gateway error on some sites that are "not allowed" in Thailand Link to comment Share on other sites More sharing options...
Chicog Posted January 29, 2017 Share Posted January 29, 2017 Browsec normally fixes that. Link to comment Share on other sites More sharing options...
alocacoc Posted January 29, 2017 Author Share Posted January 29, 2017 In my case it's not the provider. Because, on my smartphone which is connected to the same router the sites are working. I changed the DNS but the result keeps the same. I also did flash the DNS cache. Link to comment Share on other sites More sharing options...

So you think its a local problem. Clear all browser cache scan the registry for bad or corrupt entries turn off firewall disable all security and plugins. The most common advice will point you away from the client because the http data carrying status codes is sent from the server. This is not always true because the client is quite capable of throwing up a 402 error locally. You failed to mention how long this has been happening. Could it relate to a change you made or something you installed. Link to comment Share on other sites More sharing options...

Could it relate to a change you made or something you installed. Clear Browser Cache: Done Scan Registry: Done Turn off Firewall: Done Also scanned for malware/viruses. Same result. First time I recognized it, about 1 month ago. I thought, well, they have a problem with their server. But since a few days, some other website are affected as well. I did nothing change on the system. Even didn't install anything, apart from the weekly Windows 7 updates. I forgot to mention, when I use a free webproxy, the sites shows up. No problem. But why it works without a proxy on the Smartphone which uses the same network? The PC (actually a notebook) is always connected by LAN. I tried WiFi, same issue. Still think the problem is local.

Then Chicog was correct, adding proxy fixes the problem. There are tools to trap this but I think its best to stay with try and check method. If you take the notebook to the local coffee shop and hook up does it still happen ? Link to comment Share on other sites More sharing options...

As Chicog says using Browsec when the problem occurs usually fixes it ( in the same way as using webproxy does for you). As for comparing your phone with your PC, yes they're on the same router (as mine are) but the actual web addresses for the sites accessed via windows are likely to be different to the web addresses used when accessing via android. So they sites you are trying to access will probably be accessible on android but not on windows. As an example, a UK newspaper site has been blocked on windows in Thailand for a long time now but has always still been accessible using the app on android, when using the same router . That newspaper has recently released a windows compatible app for windows phones that can also downloaded onto windows PC's. That app is not blocked on any windows PC either but is still blocked using the normal web address. Link to comment Share on other sites More sharing options...
