1)My hosting company installed the SSL certificate.
2)I did Redirect HTTP to HTTPS using the modification of the .htaccess file
3)I Updates Hard-coded HTTP Links using “Better Search Replace Plugin”.
4)I did change the URL in the wordpress general setting
My hosting company use HTTP/2 for the site running with SSL, I do not know, maybe it can be the problem ?
After these change, the app didn’t work.
Yes the app was working fine before.
