Problem during Server Connexion

Associate III


I'm using STM32CubeMX 4.24.0 (I know, extremely old but I need this version to be able to follow along a course) and JRE 1.8.0_351 on Ubuntu 20.04.

It seems the tool cannot find updates or other necessary STM32 Cube packages, with the following error:

2022-12-30 12:09:05,402 [ERROR] ServerAccessManage:932 - Problem during Server Connexion : IO error No appropriate protocol (protocol is disabled or cipher suites are inappropriate)
2022-12-30 12:09:05,403 [ERROR] ServerAccessManage:419 - Problem during Server Connexion : :

How could I fix this problem?

Hello @CGalv​ 

First let me thank you for posting .

There are a few potential causes for this issue:

  1. Network connectivity problems: Make sure that your computer has a stable internet connection and is able to access the necessary servers. You can try pinging the server or accessing it through a web browser to see if there are any network issues.
  2. Firewall or proxy issues: If you are behind a firewall or using a proxy server, make sure that the necessary ports and protocols are allowed and that the proxy settings are configured correctly.
  3. Outdated software: If you are using an older version of JRE or STM32CubeMX, it is possible that the tool is not compatible with newer servers or protocols. In this case, upgrading to the latest version of the software may resolve the issue.
  4. SSL/TLS configuration issues: The error message mentions cipher suites, which are used to establish secure connections using SSL/TLS. If the cipher suites being used are not compatible with the server, this could cause a connection error. In this case, you may need to modify the SSL/TLS configuration to use different cipher suites.
