Unsupported or unrecognized SSL message

Le | Last updated: Jun 16, 2023 02:41AM UTC

I have been trying to scan some of CTF challenges but whenever I try to use chrome in Burpsuit to scan, I get this message: "Error Unsupported or unrecognized SSL message" I've tried to import the CA certificate in "burpsuit/" but it didn't work. Please support me. Thank you.

Hi Are you using Burp's embedded browser or an external browser? Could you send me your diagnostics information at support@portswigger.net? You can find this by going to "Help > Diagnostics" within Burp.

Please can you post the solution. I'm also doing some CTFs and have the same issue.

Hi all, Could you send me your diagnostics information? You can find this by going to "Help > Diagnostics" within Burp. Does this issue occur with any other site you try browsing while using Burp Professional, or is it just happening with the site you are trying to test?

Hi Can we please get an example domain of where you are experiencing this issue so we can test this ourselves?

https://buuoj.cn/challenges#[GXYCTF2019]Ping%20Ping%20Ping Visit this site, click the blue box in the left with words "[GXYCTF 2019] PING PING PING", then click the small blue box with words "启动靶机". Visit the URL of the target drone shown in blue, the URL looks like "http://4871c69c-bedd-43fc-b366-e7cddee51310.node4.buuoj.cn:81". If you use the embedded browser of Burp Community, you will face the error named "Unsupported or unrecognized SSL message". Thank you for your help.

Hi Thank you for those steps. Just to ensure we have the full picture, do you receive the same SSL error when using an external browser proxied through Burp? (https://portswigger.net/burp/documentation/desktop/external-browser-config)

Hi Dominyque, It is with the embedded browser.

Dominyque, PortSwigger Agent | Last updated: Nov 22, 2023 07:50AM UTC

Hi Dennis Can you please provide some more information on the issue you are experiencing? When do you encounter this error? Are you scanning or browsing a site? Does this error occur with one site in particular, or is it all sites?

Hi Amotz Are you scanning or browsing the site (https://tryhackme.com/r/room/wonderland)? Can you email to support@portswigger.net with the following: - A screenshot of the browser when you attempt to navigate to that site - Can you please take a screenshot of the Event Log (with the debug filter enabled) after attempting to navigate to that site? - Could you send me your diagnostics information? You can find this by going to "Help > Diagnostics" within Burp.

Hello, the error occures when trying to acess a ctf challenge though chromiom. This is one of the many sites that cant be reached when using the embeded browser: https://titan.picoctf.net:54422/ ERROR message: Unsupported or unrecognized SSL message You are not going to be able to acess the website because it's a temporary url, that closes agin after 20 minutes because it's a CTF. And i am able to load the website when using a regular browser on the same computer.

Hi Leo If you use an external browser proxied through Burp, do you still experience the same issue? (https://portswigger.net/burp/documentation/desktop/external-browser-config)
