Hola @javierbuilder,
I think this is a configuration or perhaps a library issue on your server. Try searching for the message: tlsv1 unrecognized name
I would recommend reproducing the issue outside of OJS, but within the PHP/Guzzle environment. I made a similar recommendation on this thread, where there’s a link to a suggested test script. For the test URL, I’d recommend using https://pkp.sfu.ca/ojs/xml/ojs-version.xml.
I suspect you’ll be able to reproduce the error without all the bulk of OJS to cause confusion, and this might be helpful in e.g. working with your server admin to see whether there’s an out-of-date library or similar. At least it’ll help isolate the problem.
