I've migrated to 5.1.1 and here is what my defines is at. I'm still getting the no cipher overlap problem with the latest. Wireshark capture of TLS1.3 attached.

I finally got the wolfSSL 5.1.0 integrated into Harmony 3 and then compiling. I manually replaced the wolfSSL directory into the Harmony 3 folder set and then let Harmony generate the code using the updated library. When I finally got through all of that the remaining problems were:

internal.c hadn't updated and #include <system/sys_time_h2_adapter.h> instead of #include <system/tmr/sys_tmr.h>
ssl.h didn't have the correct path to compat_types.h
hmac.h didn't have include for types.h
settings.h hadn't updated correctly
wc_port.h hadn't updated correctly.

After figuring those out I was able to get it to compile with 5.1.0

Using TLS 1.2 get the following wireshark when I use a browser. wget hangs like it did before.

TLS 1.3 continues to have the same SSL_ERROR_NO_CYPHER_OVERLAP with FF. Wireshark looks the same.

TLS 1.2 wireshark capture

Hi Kareem,

I've added the two lines in my TLSv1.2 and TLS1.3 builds and getting the same behavior on both. Since I would prefer to be on 1.3 here is the wireshark capture using that. I'll add a 2nd reply with the one for 1.2 since I don't seem to be able to add two files.

I would have to make substantial changes for the stand-alone to work on my hardware so that's not really an option.

I went back and started over adding one tiny piece at a time. I got up through the http net server working when using unencrypted http. With that working the http events were as follows:

[12/29/21 14:46:54] HTTP Net Client Open: 2, info: (null)
[12/29/21 14:46:54] HTTP Net File Serve: 7, info: dumb_page. html
[12/29/21 14:46:54] HTTP Net File Close: 8, info: dumb_page. html
[12/29/21 14:48:52] HTTP Net Client Close: 6, info: (null)

The page worked on a variety of browsers and through wget.

When I enable support encryption and server encryption in the Presentation Layer it stops working. The default encryption is TLS1.2 instead of 1.3, but if it worked I could live with it. With a browser I get the certificate warning and I can view the wolfSSL certificate, but it never serves the webpage.

wget tries to make a single connection and gets stuck at:

Connecting to 192.168.1.164:443... connected.

Only the HTTP Net Client Close event shows up when I stop the stuck connection. I've attached the wireshark for a wget connection.

Hi Eric,

I'm trying to add a HTTPNET server to an existing product which already has FTP server and UDP sockets in use for it's other functions. This means I'm trying to use the sample projects to correctly add all of this into a more complicated project.

I'm not getting any successful connections on the server. When I try wget I get the following results.

$ wget https://192.168.1.98
--2021-12-09 15:13:02--  https://192.168.1.98/
Connecting to 192.168.1.98:443... connected.
OpenSSL: error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure
Unable to establish SSL connection.

FFox is giving this: SSL_ERROR_NO_CYPHER_OVERLAP

I have found and tried some forum comments related to adding the curve 25519 in various configurations but it hasn't helped. I'm kinda leaning on Harmony for this since web and encryption are outside of my experience.

wolfSSL v4.7.0
FreeRTOS 10.3.1

I'm adding a web server to an embedded product which uses the Microchip PIC32 processor. This is my first project with an embedded web server and the associated TLS. Using Microchips Harmony 3 I added the server and encryption and got it compiling and not crashing when making a browser request to the web server after increasing the heap size.

The problem is that whatever I do now I keep getting a Handshake Failure (40) when trying to connect to the server. I've attached a screenshot of the wireshark capture and the wolfSSL config. Any pointers would be greatly appreciated.
