Hi,

You can use CAT alright: you just need to upload the cert of the issuing
*CA* - not the server cert.

I.e. the cert with the name

Subject: DC=ie, DC=Marine, CN=mica

However, looking at the server cert you attached, you will not have much
luck with contemproary client operating systems. The server cert is
still signed with SHA-1 which is not acceptable on many OSes any more.

Your CA can issue a new server cert though, this time signing with SHA-256.

Once the CA is in the system, you can also run a comprehensive set of
checks against your cert chain with the "Check realm reachability"
button. These checks warn, among others, of SHA-1.

Greetings,

Stefan
