curl does not have same result as browser - ssl

Question

I am trying to download the following URL using from command line using curl. If the same URL is requested through the browser, it is able to fetch the image. But for curl, the server terminates the SSL handshake. Just to use exact same parameters; I tried the curl commands from 'developer tools' from google-chrome and firefox. But both fails with following error.
This question was asked before here here but there is no answer that works. I tried -http1.1 as suggested but did not work.

Answer 1

it appears that floridakeyswebcams.tv requires TLS1.3 support, use the --tlsv1.3 argument,
curl --tlsv1.3 -v 'https://floridakeyswebcams.tv/sloppycam/camarchive/0807.jpg'
here is what i get when using --tlsv1.2:
$ ./CURL.EXE https://floridakeyswebcams.tv/sloppycam/camarchive/0807.jpg --tlsv1.2 -vv

and here is (roughly, it was printed in the wrong order for some reason) what i get if i use --tlsv1.3:

question still remains about why this wasn't auto-negotiated tho, i'm not sure but i guess your TLS backend doesn't support tlv1.3, and that probably has something to do with why you just got a cryptic error..
