Thank you for your support.
I set up my DNS yesterday evening, all worked well until I had this message and then I tried looking to my CPanel SSL/TSL and SSH Access to solve the issue, (I’m a complete newbie in HTTPS and SSL notions), I thought the problem was apparently Certif was ‘self signed’ so not enough for security… I gone to Certificate (CRT) – Certificate on server – and click ‘install’ …
error message:
NET::ERR_CERT_AUTHORITY_INVALID
problem of certificat SSL? what could I do?
