SSL common name certificate error

Hi there,

Trying to setup a mail client but it is continually complaining about the certificate having the wrong common name, but I have entered exactly the same server name as in the certificate, and verified this using ssl on command line to download the certificate. Any other hints on why a client might go crazy about this?

Using outlook as the client and 0.2ba as server version.

Cheers in advance,

What version of Windows, Is Windows fully updated, and did you generate the let’s encrypt from the SSL page in the admin panel?

Yes it is a lets encrypt generated cert.

Fulll updated windows 10 (see this on two machines) and also an iPad.

Can you please DM me the URL to your box that is having the issues? I will look at the public cert from my end.
