I’m transferring large files with secure Websockets, and get these kinds of errors with files larger than something around 1MB:

thirdparty/mbedtls/library/ssl_tls.c:3472: mbedtls_ssl_flush_output() returned -26752 (-0x6880)
thirdparty/mbedtls/library/ssl_tls.c:8629: mbedtls_ssl_write_record() returned -26752 (-0x6880)

The transfer appears to complete regardless.

I don’t know enough about the Project Settings->Network->Limits to know if there is a special combination of limits that will stop the errors. Also, whether these errors should be worried about.

For example, does Max Buffer Po 2 have anything to do with Websocket limits and what is the range of that setting?

Thanks in Advance

Try doubling all of them and see if it improves :slight_smile:
