Using Let's Encrypt certificates


Just want to bring to the attention of other users out here, to use let's Encrypt certificates on SonicWall devices you have to either delete the imported ISRG Root X1 which is cross signed by DST Root CA X3 or you can make sure when requesting a certificate using an ACME client to specify the issuer should be just ISRG Root X1. Otherwise the Sonicwall doesn't validate the certificate.
