B4J Question VPS ssl on port 8000 for a b4j webserver

yfleury · Apr 14, 2023

Because this subject was beginning here
https://www.b4x.com/android/forum/threads/vps-jar-error.147321/
But there is not the right subject and to be confusing, so now it's was right place.

I have a VPS server and a b4j webserver running port 8000
On my local computer, I create a keystore and upload it on vps.
Now I can acces to my b4j webserver on vps by https on port 8000. But I receive a warning the browser will not trust the certificate

On VPS I use Let's Encrypt on port 443 and port 80 is redirect to https (443)
So I can download .pem file
I can have acces to

CSR

like this

-----BEGIN CERTIFICATE REQUEST-----
MIICqDCCAZACAQAwHDEa
....
....
auJxKwzQyE+4xhHWyQotdN2QmnPtmcyZfdaSq8NwREK5baJeE3/rbyrb0WNQ9nad
lD2/ugslDfJtLYPI
-----END CERTIFICATE REQUEST-----

Private key (*.key)

Certificate (*.crt)

CA certificate (*-ca.crt)

Then now I am stuck here. Can I do something with keystore and theses informations (Let's Encrypt things)?
What is next?

Invalid password argument "236541"
Error getting passwords

It' so difficult and painfull, I am about to do my huge app in php just to have a certificate run on app.

The first time is always difficult. But its probably my mistake...
