How to import certificate chain for Hotspot Captive Portal

Hi everyone,

sorry if this topic has already been discussed, but google didn’t point me on the right topic:

For our Captive Portal we have a ssl certficate that requires a certificate chain. I uploaded the SSL-certificate (key + certificate) in an pem into the mikrotik. So far so good.

In a second step I uploaded the certficate chain to the mikrotik as well.

All the certificates are being shown (System → Certificates) correctly but the certficiate chain isn’t shipped out to the clients.

Any ideas on what I did wrong?

If you import the CA-chain before importing the server certificate then everything is fine…
