Failed to read HTTP response header!

[mf1x]

Hi,

I successfully flashed my ESP32 box a couple of weeks ago.

Today I tried adding new Tonies to the box. They show up in the Teddycloud server UI and are added to the my.tonies.com portal.

Unfortunately, I get the "Owl" error after placing new Tonies on top of the box and it fails to download/play the new content.

I am using the latest Teddycloud Docker image.

The logs say the following:

I checked and the Teddycloud server can make outgoing connections. Also checked my firewall and requests to IPs behind prod.de.tbs.toys go out as well.

Does someone have any ideas?

Thanks in advance.

I don't think this is a problem with teddyCloud but with your environment.
Please enable the pcap dump and then you may check which kind of data teddyCloud receives and cannot handle.

I get the 304 error when using Ubuntu Docker and Teddycloud for Windows. At first, I thought it was my firewall but after testing the Windows version with a mobile hotspot I got the same error.

My next thought was that my certificates were not valid. After setting up multiple containers and a lot of testing, I used the ESPTool to flash the original unpatched firmware back onto the Toniebox.
The certificates I used for all my tests were the ones from the original unpatched firmware.

With Wireshark, I can only see a couple of TCP Retransmission and Port Reused errors.

Reverting the box to the original firmware worked without problems and I can get new content from the Tonies cloud again, so my certificates must be fine.

I might try it again in a few months, and I hope the issue is gone.
