Mongoose as https client fails to download larger files ~ 6kB

[jcorporation]

• My goal is: Use mongoose as http client to download small images
• My actions were: I implemented the http client as in the tutorial https://mongoose.ws/documentation/tutorials/http/http-client/
• My expectation was: Mongoose receives the always the complete image
• The result I saw: Mongoose reads not the complete image. I added logging for hm->body.len and the Content Length header of the HTTP response:

20:36:44 DEBUG    webserver       src/web_server/proxy.c:221: Got 5468 bytes from connection "72", response code 200
20:36:44 DEBUG    webserver       src/web_server/proxy.c:226: Connection "72": Content-Length: 6022

Downloading this image works with Mongoose 7.14. The failure occurs with Mongoose 7.15.

To validate that is not a bug in my code I used your tutorials/http/http-client do download the image and got the same error.

You can find attached the log and the diff of the http-client. I compiled it with make CFLAGS_EXTRA="-DMG_TLS=MG_TLS_OPENSSL -lssl -lcrypto".

• My question is: Seems to be a bug? Do you need further logs?
