Lets encrypt not working

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

Sometimes you just need to restart your browser to see new connection

Otherwise, what browser and oper system are you using. And what versions of each?

its firefox 96.0.1 (64-bit) but in microsft edge works fine.

Have you rebooted the PC?

@kodermanews ...
you have several declarations in your html calling for insecure image resources.

EG: <a href="#"><img src=http://placehold.it/254x150/3498db/f5f5f5/&text=New+Collection" class="img-responsive" alt="product 1"></a>
