SSL Unifi server

hi i set up a unifi server on ubuntu machine. and I have purchased a ssl certificate

But when I have to put the last thing in, I get this wrong part what should I do

root@unifi:/usr/lib/unifi# sudo java -jar lib/ace.jar import_cert /home/user/unifi_test_com.crt /home/user/

Unable to import the certificate into keystore

I have never bothered installing on , but Willie Howe made an updated video about how to fix errors in the newer version.

Any reason why you didn’t just go with letsencrypt?

Thanks so much

Now work it

I had trouble getting let’s encrypt to work,

But now it works with namecheap
