I got this error from a JWT dependency package when trying to connect to an API :
"Uncaught Jose\Component\Checker\InvalidClaimException: Unknown issuer"
in "\vendor\web-token\jwt-checker\IssuerChecker.php"
Application was working fine for a year but this error appeared from one day to another without I modify my own code nor update my dependencies.
The API is working fine for other people.
Note that I connect to the API from a WAMP on my personal computer (localhost / no domain / no SSL)
I tried to understand the issue but found little on the Internet.
Can it comes from my Self Signed SSL certificate?
