Warning Code: 103 — No Response Found. Please contact with EVP Support! All connections over licenses are now passed through the encrypted protocol on EVP. So if your installation not using a proper SSL/HTTPS connection and not forcing HTTPS on domain level then this issue is very common to appear. So make sure your domain using HTTPS forced and no connection passing through HTTP/Insecure. You can modify this from our .htaccess file on public_html path. Though from EVP 3.0 .htaccess is already allowed with HTTPS value. Make sure our script htaccess is not modified by your web panel and stays intact as given. Also, make sure you are not using any ModSecurity and Firewall. Whitelist all processes of ModSecurity and Firewall on your installed script path and domain. Once everything is set, it’s very important to log out from script dashboard and do a clean installation. If you don’t log out then your session warning will be still stored in the browser.
