Stopped Working When Adding Blog Behind A Proxy #181

Closed 4piu closed 6 years ago

4piu commented 6 years ago

Several seconds after pasting "https://www.tumblr.com/liked/by/username" to URL box and clicking the add blog button, the application stopped working dialog appeared, resulted in a force close. Multiple URL tested and the results are the same. The access to Tumblr through the browser works fine. The platform is Windows 10 Pro 1709, behind an HTTP proxy.

I've never tested the proxy settings I've implemented (because of the lack of a proxy), and apparently TumblThree cannot access the web and then crashes in an unhandled exception.

Did you add your proxy settings in TumblThree (Settings->Connection) too? It will not use the systems default settings. Where did you add your proxy settings before? You might have to restart TumblThree after changing the proxy settings. You might also want to give the v1.0.8.32 version a try and see if it works better since I've just rewritten the tumblr blog detector that crashed the application according to your message above.

Here is someone who had to add the proxy port in TumblThree for using a VPN.

Thank you for the reply. I approve that the issue is proxy related. I tried the v1.0.8.32, the TumblrThree did not crush and successfully added the blog. However, it does not use the proxy as well. The blog appears offline. And when I add or crawl the blog, there is no verbose log in my proxy application suggests the TumblrThree uses the proxy. In the settings, I filled in "Proxy: http://127.0.0.1 Port: 1080" the same as all the other apps. Thanks again for your help.

johanneszab commented 6 years ago

Could you try and add only the IP without http:// to the "HTTP Proxy" textbox and in the "Port" textbox just the port. So for you case above that would be:

HTTP Proxy: 127.0.0.1 Port: 1080

I've just tested it with some random proxy I've found on the internet and it seemed to work.

4piu commented 6 years ago

This solved the problem. Thanks a lot.

johanneszab commented 6 years ago

Thanks for testing.

I'll update the description of the proxy host/proxy port textbox and allow hosts with http:// in the next release.
