"Error: SSL intermediate chain is not valid" - external CRT installed

I followed your FAQ, but it didnt help.
I try to install my external SSL certyficate. I get the CRT, KEY, CA and put it in the fields hestiaCP.
The error appear: “Error: SSL intermediate chain is not valid”

  1. Cloudflare proxy is disabled
  2. cloudflare in development mode (bypass cache)
  3. try to reboot system,

The same problem is when I try to put another SSL certyficate to subdomain: “mail.”

I have moved my domains to my home server (fresh install) and ran v-restore-user, I get exactly the same when trying to create a self signed certificate for the my new domain.

this is what I get in the error.log

v-add-web-domain-ssl  'User' 'tempest-solutions.org.uk' '/tmp/tmp.YYEKJev2nC' 'same' 'no' [Error 3]
