Hi
I have a problem playing video files from a remote media server (NAS Storage). on my iPhone. Pasting the shared link in VLC for mobile, version 3.3.12 (447) returns "Payback failed". The same shared link can be played on my Mac Book, VLC Version 3.0.17.3 Vetinari (Intel 64 bit). I mention that the Mac Version, prior to play the file warns me it is about I am going to access an insecure site with no valid CA certification, but after accepting it, the file can be played. The mobile version doesn't warn me at all, it simply displays "Playback failed"
Can anyone tell me where could I find the VLC log on the iOS version of the App, or how could I troubleshoot this issue?
Thanks!

Hello, thank you for your feedback!

In the Settings view, at the end of the settings list there is a "Lab" section where you can find an option you can enable in order to save the debug logs on the device you are currently using.

Then, go to the Files application, select the VLC folder, you can then find a folder called "Logs".
This is where the debug logs are saved.

Thank you very much for answering me! I tried to add a log but the message contains too much characters, so I will split the log in two
Couls anybody help me with this CA Certificate issue? Thanks!
