When I opened this ticket, I had enabled MPRIS. Your first screenshot shows "System settings -> Media controller", and that's not the option you should see. Take a look to my "Shortcuts - QMMP - Y1206_125340.webp" screenshot. That is the option you should look at. It's the global QMMP options, not the systems multimedia control options, which are the ones that correspond to your screenshot.
Finally it seems solved removing "forsecurity.es" from proxy
I sang "victory" too quickly ... after rebooting and having enabled the new value for no_proxy, the problem is still the same. I'll keep thinking about it ...
I have found the problem, and it is not related to QMMP. I checked that with QMPlay2 I had the same problem and it was solved in the same way, so I went back to review the values I used in the proxy, and I discovered that the sequence "0,1,2,3,4,5,6,7,8,9" was wrong, even though I read a long time ago that they were correct in a specific forum. As those values were incorrect, the system didn't know how to interpret them and finally the local domain resolution was resolved correctly. I changed that...
Good news. Thanks to your suggestion, I can play ALL (even local DNS resolved) streams. However, with what I am about to tell you, you will notice that there is something more strange and maybe that is the reason why QMMP ignores by default the proxy parameters that I have set in its configuration. If I use no_proxy="" qmmp, the problem was not solved. As I noticed that this environment variable is declared with the same value also in upper case, I tried with NO_PROXY="" qmmp and it was not solved...

Oooops ... thank goodness you explained it to me. It hadn't even occurred to me that I could try it that simple. Thank you very much! As soon as I try it on Monday, I'll write here what happened.
Is HTTP proxy. I'll try (not sure if possible) to disable "no_proxy" on monday. Thanks for suggestion
