Android client loads feed without any issues


Feed works fine here…


Worked fine for me as well till today.

Now empty response - but status is 200

No errors in logs, and I have no idea how to debug


What have you changed since the issue started?

I don’t think the latest updates would affect this, but if you roll back a few commits (to before the mailer changed–just temporarily because of the security issues) does it work?


op, i’m not seeing any error logs (preferences -> system)




Error in browser console


I have installation updated after I have seen this issue


Could you maybe rephrase that, I don’t understand.

  1. I have noticed the issue today, before updating tt-rss installation with latest git updates
  2. Then I have updated tt-rss installation
  3. Issue still occurs


The JSON response is basically empty so I’m guessing it’s failing before it can do much. Can you change the log destination in config.php to an empty string and try again. Then see if anything shows up in the log files on the actual server?


zero length JSON response without any logged errors in tt-rss (and i assume neither in nginx/apache error.log) could indicate some kind of MITM being triggered by data, i.e. an antivirus on your PC or a filtering proxy.


I dont think so

curl request on the box
