Hi all; the SSL is now working on my cloud. I thought I would share the procedure and challenges encountered.
Step 0.
Buy a genuine SSL certificate
Step 1.
Generate a CSR to request a certificate from a recognised CA
Step 2
Generate a file.jks; on my case I used keystore explore to create a keystore.jks and load all my certificate in it.
Setp 3
I then imported it into my mango /opt/mango/overrides/properties
Challenges:
After all these steps, when I edited my env file to activate the SSL, my web page couldn’t be access. The issue was on my env file, I didn’t uncommented the ssl.key.password. I followed the instruction for using certbot which was not the right one for my case. The right is on support under configurationinstallation

1. ssl.on=true
2. ssl.port=443
3. ssl.keystore.location=[YOUR FULL MANGO PATH HERE]/overrides/keystore.jks
4. ssl.keystore.password=[leave empty if you didn’t use a password]
5. ssl.key.password=[leave empty if you didn’t use a password] (Note that this need to be uncommented as it is initially commented out)
   Then I restarted mango, and that’s it

@craigweb Thank you; Port 8080 is being used and that was the isssue.

Hi all; I came trough this issue where my mango wouldn't start. I'm running it on a windows and it has been working before. I checked my java_home and I'm still pointing to the right path. I have attached the log file for more info```

@craigweb Hi!thank you very much ,this information was really helpful. Working now

@craigweb

I downloaded the full cores now, but still facing the same issue. looks like it can't see it as a zip file

Hi @phildunlap and @CraigWeb

I re-downloaded mango 3.6.4 and tried to run the unzip file from my mango folder and still no success. See the screenshot, you can see my zip file is in my opt/mango directory.

@phildunlap Hi phil! I downloaded it already 3 times, but having the same issue.

@CraigWeb: Hi Craig why is the file name different from what I've got from the website? When I ls in my linux the file I finds is a 'm2m2-core-3.6.4.zip' can you perhaps tell me if I pointed to the wrong link when downloaded?

Good afternoon!i ve been trying to install mango on linux ubuntu after following all the steps . i did create a directory to my system called mango but i keep receiving the following error message:

Please could you assit with the issues

Hi craigweb i did put : ssl.keystore.password=freetextpassword

Hi Graig!
Thanks for your response,I have created my keystore .jdk using windows key tool.and i pasted it in the directory as shown on the mango.i have not use a password to generate my key.
this is the link i got information from: https://forum.infiniteautomation.com/topic/3725/external-ip/7
