./nginx: error while loading shared libraries: libcrypto.so.1.1: cannot open shared object file: No

problem. This error usually occurs when the system is unable to find the required shared library file "libcrypto.so.1.1". To resolve this issue, you can try the following steps:

1. Install the OpenSSL library: Run the following command to install OpenSSL on your system:

   sudo apt-get install libssl-dev

2. Update the library cache: After installing the OpenSSL library, update the library cache using the following command:

   sudo ldconfig

3. Restart nginx: Now, try restarting the nginx service by executing the following command:

   sudo systemctl restart nginx

If these steps do not resolve the issue, you may need to check if the library file is present in the correct location or try reinstalling nginx.
