Django App TLS cert -The server's certificate is not trusted (Burp scan)

Project ID: 032b06db-5b31-4dc7-96b1-5d543f0a9a4b Hi, just run Burp scan of my website and result of scan came with TLS cert not trusted, do not know much about certificates by my domain incl SSl . I tried to check cert on DNS or SSL cert checkers, not sure where else I can verify cert ? Details for issues found by Burp scanner inform about following "Burp relies on the Java trust store to determine whether certificates are trusted. The Java trust store does not include every root CA certificate that is included within browser trust stores. Burp might incorrectly report that a certificate is not trusted, if a valid root CA certificate is being used that is not included in the Java trust store.". But I just would like to check if anyone came across this before or if there is another way I can verify my cert is trusted. Thank you, L
