Dear all,

The soulation as follow:

first of all Omada ONLY supports JKS certificate files and no more files supported. So, If you upload a wrong certificate through the web interface, the web interface won't be lunched or working as I received an error message. to fix it you have to go the Omada directory C:\Users\YOURNAME\Omada Controller\data\cer then you will find a file called jetty.jks delete this file a creat a new JKS certificate through KeyStore Explorer Software

KeyStore Explorer Software:

1- file > New - JKS

2- tools > Generate key pair - RSA 4,096 - edit name - write down all information needed CN=(omada's FQDN)

3- enter password for that key pair

4- tools > import trusted certificate - you have to add the p12 file created by your CA

note: windows CA creats PFX file, just rename the extention to .p12

5- file > save as - save it as a JKS file and enter the same password for the key pair

6- lunch Omada and make sure that you delete the jetty.jks file.

7- login to Omada comtroller then setting > Controller - then upload the JKS certificate we made and put the password then everything will be fine

Thanks and hope that it's clear for everyone
