Squeezelite-ESP32: Spotify Artwork Download Fails Due to HTTPS

[nanostra]

Hello,

I am using a Louder-ESP32-S3 with Squeezelite-ESP32 in Spotify Connect mode (cspot). Squeezelite is configured to display artworks for the currently playing tracks. I am using the latest firmware version provided at this address https://sonocotta.github.io/esp32-audio-dock/, as I did not see any release for the Louder-ESP32-S3 N16R8 on your GitHub. I couldn't find where the firmware version is displayed!..sorry...

1/ 🚨 Issue encountered

When Spotify sends an image URL (artwork) for the current track, the ESP32 attempts to download it but fails with the following error in the logs. Squeezelite then completely crashes, and I have to reboot and remove the artwork:1 option.

I (50365) cspot: requesting artwork https://i.scdn.co/image/ab67616d00001e029a494f7d8909a6cc4ceb74ac
I (50365) display: playing Chris Brown - Under The Influence
[00:05:13.786] D MercurySession.cpp:252: Executing Mercury Request, type SEND
E (50415) HTTP_CLIENT: No transport found
E (50425) HTTP_CLIENT: Please enable HTTPS at menuconfig to allow requesting via https
W (50425) cspot: artwork error or too large 0

Is there an option to force the request to use HTTP?
Is there a simple way to resolve this issue?

2/ I take this opportunity to ask another question: Can the displayed information be improved without using LMS?
I have added a 2.8" ST7789 240x320 screen, so there is plenty of space.

I know it's possible to display Album, Title, Artist, and Artwork, but beyond that, is there anything else?
Can we display the date, time, or even adjust the offset? The text is really too close to the edges.

For the offset, I think I saw something in the code, but I can't find any parameters for it!
Thank you for your great work! 😊

It's a config error from the s3 build.. As I don't provide "official" s3 build, the author should change menuconfig to enable HTTPS

@anabolyc (sonocota) has added the option... but now we have this,

I'll have to look at that, but likely there is a config to disable SSL server verification, a common issue

Indeed, in ESP-TLS, you have to:
[] Allow potentially insecure options
[] Skip server certificate verification by default (WARNING: ONLY FOR TESTING PURPOSE, READ HELP)

Thank you for your feedback.
