Images not getting displayed in PDF.

I am using barryvdh/laravel-snappy package in Laravel framework to convert html file into PDF.

It is working fine, but images in the PDF are not getting displayed.

Image path used in the html is like:

https://easydmc-staging2.s3.ap-south-1.amazonaws.com/ImagesSightseeing/2021/03/1PeocnxOb3gqlZmMSjwXDWwLiEfyq0a8KX5M4OOw.jpeg

Here is the link of html:

https://staging.easydmc.com/test?html=true

And the link to generated PDF is:

https://staging.easydmc.com/test?html=false

Earlier the images were working fine in the PDF. A few days back I had executed the command - sudo apt upgrade. I do not whether this is causing the problem or not.

I tried re-installing the package barryvdh/laravel-snappy, but no success.

Any help would be appreciated.

PHP version: 8.0

Server: Nginx

Laravel: 8.51.0

I got the solution:

First I checked whether there is an issue or not while generating the PDF using below command:

/usr/local/bin/wkhtmltopdf-amd64 http://www.google.com test.pdf

I got to know below issues:

QSslSocket: cannot resolve CRYPTO_num_locks                  ] 10%
QSslSocket: cannot resolve CRYPTO_set_id_callback
QSslSocket: cannot resolve CRYPTO_set_locking_callback
QSslSocket: cannot resolve sk_free
QSslSocket: cannot resolve sk_num
QSslSocket: cannot resolve sk_pop_free
QSslSocket: cannot resolve sk_value

QSslSocket: cannot call unresolved function SSL_library_init
QSslSocket: cannot call unresolved function SSLv23_client_method
QSslSocket: cannot call unresolved function SSL_library_init

The solution on above problem was to install libssl1.0-dev:

apt install libssl1.0-dev

So my PDF link https://staging.easydmc.com/test?html=false in original question started working now.
