Firefox doesn't recognize a certificate by Sectigo Ltd on certain Linux machines
I try to open https://botcompany.de in Firefox 74.
On one Linux machine (Peppermint 10), it works fine.
On another Linux machine (Ubuntu 18.04), I get a certificate error (SEC_ERROR_UNKNOWN_ISSUER).
Where does this difference come from? I need my certificate to be recognized on all machines.
Thanks

Hey guys, problem SOLVED.
I needed to put the full chain instead of just the certificate in my keystore (webserver is written in Java). Posting the crucial code here to help others:
cat privkey.pem fullchain.pem >priv-and-cert.pem openssl pkcs12 -export -out keystore.p12 -in priv-and-cert.pem -name mydomain.name
